Chris Tuohy (North Carolina, United States)

Thanks for the great riding on Friday. I really enjoyed the experience of riding in Marin. The vastness of the terrain is just awesome. It is a lot like riding in the mountains in NC except Marin is your backyard. I have lots of great memories, especially that switch back climb that was so hard. That's my favorite part of mountain biking-finding something really hard and trying it again and again until you clean it. I do not golf but its the last good shot in the golf that always brings you back-just like a hard trail you finally clean after riding it a bunch of times,

I can't wait to come back out and do the complete ride. I will contact you when I come back out again. I will definitely recommend you to my friends that come out and would be interested in riding in Marin. I would love to ride with everybody on one of those Friday rides.

Thanks again!

I have always considered myself a timid mountain biker until I took the mountain bike clinic that Celia teaches. This was only for women. Of all the things I learned that day, most of the tips stayed with me and I improved a lot!

We just got back from Downieville and I was so lucky (and Happy) to be with Celia on a couple of really challanging rides! I learned to let the bike just float under me as to let the bike absorb more of the punishment that my body was taking on! I also learned how to climb a rock that was like a wall and my fear of it took over until Celia showed me how to do it! I improved so much with her teaching!

Celia has a way with describing and demo-ing that makes sense! I have had folks try to teach me, and I just say " ah ha, oh yeah..." but really don't get it most of the time. I recommend Celia's clinics to everyone and anyone who wants to jump up a few notches and save time by just learning in a few lessons! Celia's approachable and humorous personality really add to the experience and fun of mountain biking...and isn't that what it's about?

For three years in a row I haphazardly entered and raced the Downieville Downhill, a challenging one-hour + downhill race on challenging terrain--the only "downhill" race with a significant climb thrown in for good measure. While I fancied myself a fairly accomplished mountain biker, the first year I was 6th out of 8, the second year I looked at a rock wrong and ended up clinging to a tree suspended over the canyon with a broken rib, and the third year I don't remember so it clearly didn't end with me on the podium.

Before my fourth attempt, I decided it was time to call in professional help. I needed to bag this thing once and for all. I had a lesson with Celia on a challenging single track in Marin, myself and one other student. Celia knew every subtle twist and drop on the route and stopped us before each obstacle so we could walk, discuss, and dissect it. Her intuitive understanding of my capabilities (and limitations) and those of my fellow student were confidence inspiring. We spent time on each section, going over and over it until it felt like a trip down the bike path.

Armed with a new resolve and skillset, I awaited my start at the top of the Downieville course, podium in my sights, and Celia's lyrical latina voice in my head coaching, goading, prodding me to finally claim this race. With Celia's help and a whole lotta luck in the form of no flat tires, I cleaned the entire course (okay, I didn't ride the waterfall....or the rock face.....) and came in 1st, a full 6 minutes ahead of 2nd place, and most importantly, fully intact with a dirt-laced smile on my face.

Many many thanks to Celia for teaching me to take the time, and for her keen understanding of when to scream at me (lovingly), and when to say "we'll do it next time".

Celia rules! There is no one I would rather ride with when trying out a new trail or skill for the first time. I've been lucky enough to attend many clinics and rides with Celia, and I always come away with improved skills, increased confidence, and joyful memories. I always feel safe when riding with Celia - she's an excellent judge of skills and abilities and I know that she'll never try to take me down a trail or obstacle I can't handle. She's really friendly and encouraging - if you're out with her on the trail, you are guaranteed to have fun! She doesn't tolerate any "hammerhead" nonsense, and creates a mutually supportive, non-judgmental environment on each ride. With her help, I've been able to ride trails I never thought I could ride, and I have a blast every time. I wouldn't be the rider I am today without her. Thanks, Celia!!!

Thanks Celia! You are an amazing teacher, you inspire confidence and you really know how to break skills down so that they are easy to understand and master! I have learned so much from riding with you over the past several years, thanks!

Celia's clinics are awesome, they can help anyone at any level improve their mountain biking skills. You'll be riding better and faster and down steeper descents than you ever imagined!! Celia knows all the great trails and fun spots in Marin and in the Bay Area. And you can't beat the views from the rides she takes you on and best of all you'll never get lost when you're with Celia!

Celia Graterol is a fantastic biker, leader, trail guide and organizer. The cross-country mountain bike tour she put together for me was a great day of riding and worth every penny! I can strongly recommend her services.

There is very good biking where I come from in the southern alps of Europe. But when a family gathering gave me the opportunity to be for two weeks in the San Francisco area, the chance was too great to pass up: I had to go bike riding in Marin County.

But how does one just "go" to a place and start riding there? I needed a bike (transporting mine from Europe would have been too complicated and costly) but more importantly I needed to know where to ride. I didn't feel like getting lost in the hills during my holidays.

Celia Graterol organized some of the best holidays I have ever had! Celia is a great rider, both cross-country and downhill, and she is also good at working with people. Even more important, she knows every nook and cranny of Marin County and she is a thorough organizer.

I have to admit I did not know what to expect when Celia and I finally met for our first ride on a cold (by California standards) sunny, wintery morning at China Camp. A lot of things can go wrong on a bike tour, especially when you're organizing for someone you don't know. But Celia had thought of everything. She organized an amazing bike for me that was the perfect fit (the many email exchanges regarding measurements and body size paid off), and through her thorough questionnaires she had figured out exactly what kind of biker I was. Celia knew the terrain so well, and she had exhaustively researched what kind of day-ride I wanted. She was also a supportive bike partner. She listened and watched, but was not scared to comment on my biking technique, and I learned a lot!

It was a day of riding that I will never forget.

In Slovenia and Austria there are some incredible downhill rides because the mountains here are very steep. When I had been previewing Marin County on google maps I noticed that the hills were not so high compared to the alps, so I was a little skeptical at first about what I consider the fun factor (I love downhill). But the rolling hills of Marin County are unique and completely special, something that everyone who loves mountain biking should try at least once in their lifetime! The easy, undulating pace is so satisfying that the singletracks seem to go on forever. After you have ridden here you can start to understand why the sport of mountain biking was born here.

So what can I say? Was it worth it? Yes! Like I said above: every last penny. I liked it so much that two days later I had to go again...

The tour was definitely fun! Shanti was really nice and helpful, she came and got me no problem from the hotel, the transport was great, and she even went out of her way to show me the nice little town at the bottom of the mountain (Mill Valley) and also a place to get some good views of the bridge.

The bike was fine - it fitted me well and was comfortable and Shanti helped me adjust the saddle part way up as it was still too low. Shanti had a choice of helmets so one did fit, and she kindly lent me her arm warmers so I didn't need my heavy jumper.

The views and the mountain were lovely. I probably didn't realise that it was going to be such hard work climbing up for quite a while (I'd never climbed that consistently up), I think all my experience was on flatter ground / short climbs in forests / canal towpaths. But she was encouraging and once I got warmed up it was better. It was fun coming down! Many thanks.

Celia helped me discover the world of singletrack outside my door. I have been an avid rider but made the mistake of looking at trail maps and DRIVING as far as the Santa Cruz Mountains (ie Soquel Demonstration Forrest) up to Santa Rosa (i.e. Annadel Creek) as well as Downieville and Truckee for my thrills. Yes, even experienced local rider owe it to themselves to discover the hidden trails of Marin with Celia. In addition, she can quickly identify your habitual riding errors that largely go unnoticed until it is too late, when you are already on the ground. As a 40 year old, recovery from falls simply takes too long and Celia's on the spot instruction of proper technique will help you keep the "rubber side down." The mountain bike world has a very maverick appeal and as a result people are often self taught, with an occasional pointer from friends. Think about it, we think nothing of spending 100 bucks or more on a pair of riding shorts but invest little into what really matters, riding the bike. Simply put, there is a reason people are passing you on the trail, even as an experienced rider, because they have had instruction! And if you think you are too old to go both faster and safer, Celia won the 2006 US National Downhill at my age!

Thank you Celia! What a fun day out on the mountain. Your patience and humor really helped to boost our confidence for the switchback clinic. It was so great how you could recognize and then articulate each of our different and specific needs to take us to the next level of riding.
Thank you for knowing exactly when and how to challenge us just the right amount to improve our skills. With your help, riding is so much more fun now.

Celia offers a fantastic day of riding. Her local knowledge of hidden gem trails makes for a great day well off the beaten path.

Carl Coletti (San Francisco, United States)

Celia Graterol understands the physical and mental aspects of taking a person with a lot more desire than common sense and pointing them in the right direction in my case DH (downhill....).
Being a former road racer having been off of a bike for twenty years and deciding that downhill courses looked like way more fun than being on a road bike, a little voice in the back of my mind told me that i might seek some sort of instruction to limit any injuries related to lack of proper form and general trail cluelessness.
A google search for downhill instructors in San Francisco / Marin led me to Celia Graterol.
Celia's skills, patience and understanding all played a major part in my realizing my dreams of blasting down Fairfax, Mount Tam and Pacifica downhill trails hitting rock gardens, steep descents, jumps, drops, cornering and feeling comfortable and confident at speed. Celia never hesitated to walk through ...talk through...go through....review....the mental and physical barriers associated with this type of riding . Celia's riding technique and understanding of theory are only rivaled by her sense of humor and personality perfectly suited to teaching in some of the most beautiful outdoor classrooms in the world....
Celia is truly a mountain bike midwife of dreams.
My bike and i thank her for our two wheeled deliverance.

Anna Bishop (Administrative Associate, Google Earth/Maps/Local, United States)

Celia and the Mountain Biking Marin gang organized one of the best company outings we've ever been lucky enough to attend. We had as many experience levels and interests as we did participants, and yet Celia managed to plan a trip that was challenging, interesting, and mind-clearing for everyone. Every last detail was taken care of--from lunch to poison oak remedies--so we could really concentrate on bonding as a group and enjoying the gorgeous scenery. It takes a lot to drag this team away from the office for a day, but there was surprising little nervous I-Phone scanning since everyone was so thrilled to be out on the beach and in the Headlands. From our most advanced outdoor enthusiasts to first time mountain bikers, Celia ensured everyone had a great trip. Thanks for an amazing experience...we'll be back!

Tom McGraw (Chief Executive Officer, FNB BANCORP, San Francisco, United States)

I have had the delightful opportunity to ride my mountain bike through spectacular west Marin mountain trails with Celia Graterol. Celia is, in a word, wonderful! Her passion for riding is only surpassed by her skill as a guide and teacher. She takes the time to clearly describe routes and techniques on challenging trails. Her supportive guidance builds confidence in the rider and that is very empowering and Celia has a marvelous sense of humor. She's awesome.

Andrea Frias (Marin, United States)

Celia has a striking personality that makes her a joy to ride with. She never pushed me too hard and was always there to offer her years of experience to help me clear the more hairy areas. Sure, I'm a beginner, and those so-called hairy areas probably weren't too horrible, but you know what I mean. She knows exactly which trail to take you on and matches your pace so you're not pushing yourself. Her fabulous humor makes the ride all the more enjoyable. She's a wonderful teacher and I'd love to continue our lessons in the future.

Michelle Wharton (Hawaii, United States)

I had a great ride! Celia knew every inch of the trail and gave me a heads up of what was to come around every corner. At one crossing, she even got off her bike to block and wave me away from a dangerous drop. I will definitely ride with Mountain Biking Marin next time I'm in town.

Kristy DeCoursey (Sonoma, United States)

Celia, I want to thank you for being the one to answer my email for help in mountain biking. It's truly been a pleasure to be taught by you. You made the learning fun and easy, and it felt like being coached by a friend. Thank you very much. Kristy.

Having always wanted to ride the areas made famous by the Marin bike company this was a great day out. Celia can create a ride that will suit your level of riding and skill – from beginner through hardcore riders looking for technical and endurance riding.

If you are based in SF then this is a definitely worth a day out – whether you are into biking or not. Celia can collect you in town and recommend excellent bike hire. The bikes are full suspension Marins and in great condition (rare for any hire bike). The views across the Bay area from the hire shop is stunning enough but then you get driven by Celia to Marin county over the Golden Gate Bridge. The whole journey is just half an hour but you go from dramatic city skyline to beautiful countryside.

The ride itself has something for everyone and Celia will provide all the support and coaching you need. The trails offer some excellent views so make sure you take a camera.

After the ride you can stop for a beer and a chat with the other bikers who have been on the trail before you get to enjoy the same panoramic views of the city and bay as you get dropped back off in the city.

Charles Nichols (United Kingdom)

I had a totally FANTASTIC day with Celia exploring the mountain bike trails at Tamarancho (Marin county). This was the single best day’s mountain biking experience ever. Celia knows the area well, where to hire good equipment, and how to match the right mountain to the abilities of the individual rider. But with Celia you don’t just get a tour. I learned a lot from her gentle coaching style, and my technique has improved dramatically as a result, in particular dealing with ‘switchbacks’ (very tight hairpin bends to the Europeans). Her patience was admirable as I got to grip with new techniques, until I mastered these turns.

Celia is a rare find and I unreservedly recommend for individual, group and corporate hospitality tours where you’re looking for a real adventure amongst stunning scenery, and some of the world’s most exciting mountain bike trails. Five star rating – highly recommended.

Arnab Chatterjee (United Kingdom)

Celia is not only a frighteningly good rider, she knows the tracks and the trails really well. Anecdotal, interesting and relaxed, ...."she pushed me to a level where I
had been comfortable once, many years ago, by being cheerfully relentless and encouraging my competitve streak. Within a few hours, I was fully zoned in and admiring not only the technical ride but the extraordinary landscape. The actual service was flawless, with pick up and drop off, bike rental advice, post ride gps mapping and follow up emails. My only concern with this testimonial is that next time I am back, Celia will be fully booked up.

Alan Loving (San Francisco, United States)

Riding with Celia in Marin County made for a complete experience. She is pleasant, knowledgeable about the area, bikes and riding technique. Most importantly, she is patient! I would never have found the areas she showed me, let alone ridden them. Thanks for a great day. I'll be back.

Sean Benward (East Bay, United States)

Celia, It was you who inspired me four or five years ago to race. It was your positive words of encouragement that gave me the confidence and motivated me to take the first step, sign up and race. I have never looked back and I keep looking forward to the next race like a kid waiting to open their Christmas presents on Christmas morning, I am healthier and much more passionate about cycling as a result. For this, I owe you a BIG THANKS. It goes to show you how valuable a kind supporting word can be. I am honored to be part of your legacy.

Christine Schick (Berkeley, United States)

Honestly, I miss your infectious spirit and fun-loving nature, too! But when I get back I will certainly start riding with you and the ladies again. Absolutely!! And maybe you and Dana can teach me how to catch air without dislocating my shoulder.
