On Thursday, February 26 the Leap Day/Observatory Loop Relay will return for year three. This is a 4 x Mile trail relay race, where teams of two, take on the one mile long Observatory Loop. Each team will run the loop four times, with team members alternating laps, and handing off a baton at the conclusion of each lap. (That means each individual runner will do the loop two times, with a break between each loop.)
The race will start at 7pm. This means it will be dark during the race! Runners are required to race in headlamps.
You can sign up with a partner or individually (and we will place you with a partner).
This event is open to runners of all ability levels. All runners take home a branded baton.
