Signup for this membership if you want to do the 200K Challenge (included in your membership). You can add more challenges by going to the store section and purchasing another challenge.
The 200K Challenge is a larger but more flexible challenge, as you can reach your 200K goal by doing any combination of the participating races in the 50K Challenge, the 100K Challenge, and the half and full marathons on the list of participating races between January 1 and December 31, 2025. Like the other challenges, once you sign up for the 200K Challenge, you can then go directly to the participating race registration sites and sign up for those races directly.
Signup from Now until September 1, 2025 for the membership. Membership expires 12/31/2025.
