Curious about all those runners and bikers Moraga residents are going to be seeing on Saturday?

That’s the first ever Moraga Treeline Triathalon.

The event will feature a 400-meter swim at the Campolindo High School pool, a 14-mile bike ride that sends bikers out to Canyon School and back, and a 3.1-mile run through the neighborhood around the high school.

The event gets under way at 5:30 a.m., and the first swimmer takes off at 7 a.m. All proceeds are going back to the town.
