zap store seems to be down, but I've pushed the github release https://github.com/HealthNoteLabs/Runstr/releases/tag/new-features-0.6.0-20250711-013508
You can zap the announcement post I made to be added to participant list, or you can just wait for the zap store release. Either way, once you purchase a ticket your workouts saved to nostr from 07/11 - 10/09 will be counted in the competition.
Good Luck
