Jill Martindale

The tangible progress of learning how to ride a technical trail, the learning curve of bike-packing in the snow, and the community you get to know while spending time on the bike — these are all reasons why Jill can't pick just one favorite style of riding. Being able to experience the outdoors on a bicycle every season has brought so much joy to her life. Her perfect bike ride includes petting a dog, Type 2 fun, correctly identifying a bird or plant, and plenty of snacks. Jill has been racing for over 10 years, and the ski area is one of her favorite places to play.

Hey everyone! I've been a part of the mountain bike community since way back in 2007, and I'm still just as excited about it today. For the last five summers, I've had the awesome opportunity to coach mountain biking, and I truly love sharing the skills and techniques that help riders have the most fun on the trail. When I'm not coaching, you can usually find me out on the trails – it's where I spend most of my free time!

I'm also a founding member of the West Michigan Bike Patrol, and I'm proud to be a part of a group dedicated to keeping our local trails safe and accessible. I've even put my skills to the test by finishing the Marji Gesick 50 mile race multiple times. I have a deep passion for mountain biking and helping others discover its joys. Let's ride!
