South Philly 3-Hour Mailbox Madness - February 14, 2026
Registration will close at the end of the day (11:59pm) on Thursday, February 12, 2026.

What better way to spend Valentine's Day morning than with a run through the City of Brotherly Love—specifically FDR Park, the Navy Yard, and South Philly?

Join us for the last event in the third winter series of Mailbox Madness, offering urban sprint orienteering training in Philadelphia (and environs). This one is for the ages—a three-hour, multimap score-O—with lunch/Mappy Hour to follow, details TBA.

Mailboxes (and other landmarks) replace control flags. 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, time TBA. Arrive 15-30 minutes early to collect your maps and plan your route.

Advance registration is $10. Day-of is $15.
