A price change is coming - here's what it means for you

From 1 August 2026, the price of a paid subscription is increasing:

• Monthly: USD 5 → USD 8

• Annual: USD 50 → USD 80

If you’re already a paid subscriber, this doesn’t affect you. Your subscription will keep renewing at your original sign-up price for as long as you stay subscribed. No action is needed - this is just a note so the change doesn’t come as a surprise if you ever look at the subscribe page.

When I set the original price, this was a smaller project. It has expanded significantly since then:

• There are 938 research studies in the archive, spanning altitude, heat, nutrition, pacing, injury, VO2 Max, and more. This is a valuable resource comprising a curated selection of studies with simple takeaways to help you answer your endurance training questions.

• As a paid subscriber you receive a weekly newsletter, not just the first newsletter of the month, providing you with 4 times the research of a free subscription.

• Every study is broken down into what it actually means for your training with clear practical takeaways based on my coaching experience.

• The monthly SUPER PRACTICAL newsletter provides a quick summary to catch up on the practical next steps that were shared that month. If you missed anything or just want a quick review of what we learned that month, it’s available to paid subscribers.

I believe this is genuinely good value at the new price and it reflects the amount of work that goes into the newsletter each week. I’d like to keep investing and building the value of this database of research and your support helps me do that.

You have until 31 July 2026 to subscribe at the current rate - CHF 5/month or CHF 50/year - and keep that price for as long as you remain subscribed. After that, new subscriptions will be at the new rate.

Thank you for your support so far. The number of subscribers and the feedback I have received have helped build this newsletter to the point where it is now.
