San Dimas Stage Race Centerline Rules

Centerline rules apply to the Glendora Mountain Time Trial of the San Dimas Stage Race. What this means is that the rider should stay right of the yellow lines in the middle of the road. The riders are trying to find the sweet spot of the road where the curvature is less pronounced, however crossing the yellow lines is called "shorting" the course. There will be fast moving descending traffic from previous riders and there are blind curves.

I witnessed more than a dozen riders ignoring this rule (with photos) during the 2009 SDSR event. The USA Cycling Official penalized each rider with 30 seconds added to their final time.
