Aid Stations

Aid stations will have as a minimum: water, electrolyte drink (Tailwind), Clif Shot Gels and Blocs, fruit, salty foods/chips, sweets (cookies, candy, etc), soft drinks (coke,mtn dew, ginger ale), and ice. Night time aid stations will have soup, hot drinks, and sandwiches. Special needs diets must be addressed by the runner using their drop bags.

Drop bags will be transported to the following aid stations: Sunrise 1/2 (21.0 and 91.5 miles - use same drop bag for both passes); Pioneer Mail 1/2 (28.2 and 84.3 miles - use same drop bag for both passes); Penny Pines 1/2 (43.8 and 80.3 miles - use the same drop bag for both passes); Red Tailed Roost (mile 55), and Cibbett's Flat (mile 64 ). This information along with mandatory cutoff times and pacer information are located on the Aid Station Chart and the Maps / Elevation links on the homepage.

Runners will also be able to have a drop bag located at the start / finish line so as to have ready access to it upon finishing. Do not leave any valuables in your drop bags. There is an outside shower next to the Lake which can be used to wash off. This shower is cold lake water only. There is also a coin operated shower (warm water)on the other side of the Lake (1 mile from start/finish line)at Chambers Park.
