1:1 Coaching

Threshold lab is the best to be apart of, without Stephen we would not be able to keep reaching new PRs! He truly cares about his clients & can’t wait to keep pushing the limits!

1:1 Coaching

The Threshold Lab has been my best investment yet! I started working with Stephen after my first Hyrox in May 2025. Since then, his programming prepared me to run my first solo (& beat my doubles time by ~3 minutes) and PR my doubles time by 14 minutes. He truly cares about his athletes and puts in the same (if not more) effort into his clients' goals as his own. I am grateful to be a part of the TL family!

1:1 Coaching

Before working with Stephen I was just kind of training and hoping it worked. Now everything actually has a purpose and it's a completely different feeling. Going into Houston I had a level of confidence I've never had before and it showed.

1:1 Coaching

Working with Stephen has absolutely taken my performance to the next level. He’s helped me shave 12 minutes off my pro solo time. Not only this but Stephen works with my schedule to ensure I’m getting the most out of my training amongst a busy work schedule. His 1:1 coaching truly is tailored to me and I couldn’t ask for a better coach!

Billy

1:1 Coaching

I’m incredibly grateful for everything the Threshold Lab has done for me since December, especially as I’m approaching my 40s, it’s not something I take lightly to say that Stephen has truly changed my life. Balancing training with a full time job and life at home with four young kids isn’t easy, but he made it possible and kept me accountable every step of the way, while helping me achieve a goal I once thought was out of reach. Because of the Threshold Lab, I’m not just proud of what I accomplished, I’m more motivated than ever and confident to chase even bigger goals ahead.

1:1 Coaching

After competing in my first Hyrox in Dallas I was instantly hooked. I knew I wanted to go to DC and knew I had more to give and found Threshold Lab. I told Stephen I wanted to be sub 75 but knew it would be a push since my previous race was 1:21:29. Stephen helped me map out the plan and went to work for 11 weeks. Beating the goal by 10s and beating the plan Stephen helped me form by 1s. Cannot wait to see what else I can accomplish with the help of Stephen

1:1 Coaching

I met Stephen at a Half Rox event last year and started following his Threshold Lab newsletter. I was immediately drawn to his passion for data and research, and the way he thoughtfully applies it to his training approach. I signed up for 1:1 coaching ahead of my most recent doubles race, and the training structure, his methods and accountability made a big difference. With his guidance, I was able to shave over 4 minutes off my previous race time and improve my average run pace by about 10 seconds compared to my race four months prior. I felt more prepared and confident going into race day and was able to perform at a high level. If you’re looking to really dial in your training and add intention behind your work, I highly recommend working with Stephen.

16-Week Run Program

I joined the Threshold Lab app looking to improve my running for HYROX, and the 16 week run program has made a huge difference for me. The programming is purposeful, progressive, and well structured, and over the course of the 16 week program I improved my 5k time from 20:12 to 17:56, took 45 seconds off my estimated threshold pace, and gained a ton of confidence in my running. It is clear that Stephen put a lot of time and effort into designing an effective running program that helps people achieve meaningful and sustainable progress, and I have so much confidence in the program that I immediately restarted it and continue to use it for my run training. If you’re looking to improve your running, it doesn’t get any better than the Threshold Lab run program!
