A note from our founder

Our founder, Phil, hasn't crossed a swimrun finish line yet. We don't publish full guides until we've lived it — so for now, here is some basic info to get you started, with more coming.

Getting Started with SwimRun

SwimRun is a continuous race that alternates between open-water swimming and running over a series of segments. Courses string together stretches of water and land, so the number and length of the swim and run legs varies widely by event.
