Notes
Not sure if you remember, but Roger Antoniu and I started this race in Leslie Paul’s backyard. There was this giant willow tree and after the race we had a big cookout. The transition area was in the street…. Fun times. We are SO lucky to have access to this fabulous lake and the generosity of the Diamond Lake Marina to host. Transition area will be in their lot, next to the white garage. Grateful for everyone who has put in blood, sweat and fears to keep this event going! Photos below were from 2016!

COURSE MAPS
Bike Course is out and back 12 miles


Run course is out and back, with fabulous lake view and 3.3 miles.

We’re going back a few years here, the overall sailboat awards have gotten much larger!

The bike course goes around the lake, onto a country road and back. The portion along the lake is chock full of great views and gorgeous homes with lush trees!

Again this photo is of yesteryear, but you can imagine running along side the water and being lifted by old trees and great views!
