Simple solution, Have a volunteer stand Where Barr trail and the Incline trail meet and ask the hikers to wait until the all the runners or at least 90% of them pass by. This would only work for the Ascent. I do think signs should be posted on Marathon day. Runners coming down have right away and they are racing!!!
In response to:
Just amazing, Parks and Rec refuse to close the incline down for the marathon:
What possible reason can they have for this? Maybe they can't think straight because they are hanging out at Maggies Farm too much...
All I know is I'm going for a PR; so message to Incliner's, you hear me comin get the hell out of the way!
