Spring 600K - 5/28


This will be a reprise of the 2007 Summer 600 designed by Eric Vigoren - Current details won’t change but the actual route may vary.

Start will be in Tumwater - we will ride Chehalis watershed and Willapa Hills area with the goal to get to mouth of Columbia. From there route turns East to Kelso overnight. Overnight in Kelso - rooms reserved - bag drop - please use a small light bag - will be transporting in a Jetta so limited room.

Next day will focus on getting to Morton and back up to Tumwater.

Final Cue Sheet posted


Ride Summary:

This will be a lightly supported ride, there will be be food at overnight and there is a 24 hour Denny's not far off route. The route can easliy accommodate folks riding through because controls will be info or open. Secret control will have water.

Hopefully the main difficulty with Holiday weekend traffic will be for the start - be sure to schedule extra time if you are coming down in early AM.

Latest details are on the blog, http://blog.seattlerando.org/
