The Course

It's the Fifth Street Cross course at the Emmaus Compost Center (it's not a dump!), the same twisty, turny loop you know from Thursday nights, with one change: we're adding a section to stretch the lap to 1.6 miles-ish. Runners and riders are on course together all day, so stay between the tape and call your passes.

It's dark until about 7am. Bring lights if you're starting at midnight, and bring backups if you're doing the long stuff.

Laps by distance

• RUN: 10k-ish = 4 laps · Half Marathon-ish = 8 · Marathon-ish = 16 · 50k-ish Ultra = 19 · Full FSX Season in One Day (60k-ish) = 24

The map below isn't completely accurate, but as we always say, the location is correct. Stay between the tape when you get there.
