Phoenixville Mailbox Madness - January 24, 2026
Registration will close at the end of the day (11:59pm) on Thursday, January 22, 2026.

Join us for the third winter series of Mailbox Madness, offering urban sprint orienteering training in Philadelphia (and environs). The Phoenixville edition will begin in the late morning, with lunch/Mappy Hour to follow at Root Down Brewing Company. Events follow a Score-O format, with mailboxes (and other landmarks) instead of control flags. Tag as many mailboxes as you can in 60 minutes—pace and route choice are up to you. Scoring is unofficial, on the honor system, though the map will be on the Usynligo app. Note that urban running involves risk. Please cross streets safely and carefully.

There will be a mass start at 11 am; arrive fifteen minutes early (10:45 am) to collect your map and plan your route.

Advance registration is $5. Day-of is $10.
