Source Endurance

The Leadville Race Series Trail 100 MTB is one of the most iconic endurance mountain bike races in the world.

But this year, athletes are facing an unexpected challenge before they even reach the start line. As the Willow Fire continues to impact the Leadville area, many riders are wondering what it means as we're 3 weeks away from race day. https://source-e.net/rider-resources/will-the-willow-fire-claim-leadville-trail-100-as-victim-in-2026/

Congrats to Source Endurance athlete Beric Cantwell on his recent success in the Horner Foundation Crit in the Junior 13-14 category!

Coached by Adam Mills, here's more from Beric on why the race was so special, "I have never tried to go for a break and to do it solo in a different place feels pretty good."

Congrats Beric, we're so stoked to be a part of your journey!

Congrats Tim Smith, on taking 3rd in the Lost and Found Gravel race in the 71-80 age group.

Here's more from Tim on the race, "I feel fortunate to be able to still ride and compete at this point in my life. Getting on the podium is a bonus, and in this race, eight minutes separated first from third over a 58-mile course.

Lost and Found is always a challenging, rough course, and on this day, we also encountered high heat. On the final climb, about mile 50, I encountered a high heart rate and lost contact with the two leaders. Overall, a great day on the bike!"

Love to hear it Tim. Keep on rolling!

Dehydration is the leading cause of DNFs at gravel events. So if you are going into a race this summer, you'd better have a hydration strategy.

Consistency wins. It's not the occasional epic ride or one perfect workout that makes you a stronger cyclist—it's the weeks and months of showing up, putting in the work, and sticking to the plan.

In this article, Source Endurance Coach Adam explores why consistency is one of the biggest predictors of long-term performance and how small, repeatable efforts can lead to major gains over time.

Congrats to Source Endurance athlete Marlaina Zubchevich on taking the W in the Cat 2 race at Eldo last month.

Here's more from her on how the race unfolded: "This win was special because it was my first of the season and a great reminder of how valuable local races can be for developing race craft. Racing without teammates, I counterattacked halfway through the first lap, into a corner that led directly into a strong headwind. When I looked back and saw I had a decent gap to second, I wasn't sure I could hold it for 40+ minutes.

Instead of panicking or giving up, I focused on trusting my training, staying calm, and committing to the effort. Something I discuss often with Coach Adam is having the confidence to commit to the move, and I was happy to claim the top step by putting the training to work!"

Great work girl, way to trust the process!
