Congrats to Source Endurance athlete Scott Johnson on returning to racing and taking the top spot at the STF Epic Half Pie!

Coached by Adam Mills, here's more from Scott on the race: "Maybe one of the most gnarly gravel/road races I've ever done, conditions-wise. Turned into a long CX race with the extreme mud. This was one of those races where it was more of a mental battle. You kinda just had to make peace with how bad the mud was and get on with it. The spray made it very hard to see, and it was difficult to keep the bike upright for a lot of the race."

Way to power through it Scott! Coach Adam is so proud.

1st gravel race in the books for Michelle McAllister! Coach Adam is proud to see you get out there at the Village Gravel Race.

From learning the techniques needed to race in gravel, to dialing in your race strategy to get to that finish line, we can't wait to see what you do next season. Well done!

Here are 5 reasons to work with a cycling coach this fall:

1. Establish achievable goals.
2. Build your foundation.
3. Address weaknesses.
4. Adjust your training to your schedule. Work, travel, family and recovery all matter.
5. Have someone in your corner to help you stay accountable, know when to push, and when to back off.

Talk with a coach, ask questions, learn how our process works and see if it’s a good fit before you commit. https://source-e.net/coaching-consultation/

You’ll be putting in the base miles soon. But are you planning your next season strategically?

A strong season starts by working backward from the events that matter most.

Start with your A goal. What performance matters most to you this year?

Then build the timeline. How many weeks do you have to prepare, and what needs to happen along the way?

Consider the demands of your event. What level of fitness, endurance, power, fueling, skills or race-specific preparation will it require?

Know your limiters, too. Training time, recovery, strength, fitness and experience all play a role. Your plan needs to account for the reality of your life, not just the demands of the event.

Finally, build your progression. Your training should move you toward the demands of your goal rather than simply accumulating miles and hoping for the best.

And remember: last year’s training plan isn’t automatically the right plan for this year. Your goals, schedule, fitness and life have changed.

Congrats to Source Endurance athlete Scott Johnson on returning to racing and taking the top spot at Capital City Cross!

Coached by Adam Mills, here's more from Scott on the race, "I didn't ride from 2022-2025 due to injury and my last CX win was in 2021. It was a long road to be healthy enough to ride again at all let alone be able to race and be competitive.

Winning the first race of the season in tough conditions was a big confidence boost that I've gained my fitness back and can keep building."

Way to get back to doing what you love Scott! Coach Adam is proud.

VO₂ max and lactate threshold testing give you a much clearer picture of how your body is performing, and the data to make decisions about training intensity zones and progression.

And you don’t have to be an elite athlete to benefit.

If you’re putting in the hours on the bike and wondering whether your training is actually moving the needle, testing can give you a valuable baseline and help you understand where you are now, and where you can go next season.

Fall testing appointments are already booking into December, and availability is limited.

Learn more and reserve your testing appointment:

In collaboration with the San Diego State University we are able to provide athletes and individuals of all fitness levels with access to state-of-the-art exercise performance VO2 Max and Threshold testing services as well as DEXA scans

Open Instagram and suddenly it seems like everyone is riding more, recovering better, racing faster and stacking up impressive training weeks.

But here’s the thing: You’re seeing a highlight reel. Not the whole training picture.

Your training needs to work for your goals, your schedule, your life and your body. So before you add another five hours to your training week… take a step back.

Coach Zack takes a closer look at goal setting, social media and the overwhelming amount of data available to athletes.

You’re scrolling the gram, you look up intermittently and look out your window. The weather is either absolute trash, or you're feeling firmly imprisoned by your day job. You look back down at your phone and you see, yet another proud screenshot, of someone’s 28 hour riding week with 1520 TSS po...

A successful season starts with a plan. When you map out your year, you can identify your key events, build appropriate training phases, schedule recovery, and make sure you're arriving at the races that matter most with the fitness you need.

It also helps you avoid one of the biggest training mistakes: trying to be at peak fitness all year.

You can't peak for everything. And you don't need to. Instead, think about which events matter most to you—and build your season around them.
