The Pikes Peak Ascent and Marathon are this weekend (Aug 20-21, 2011). The Ascent is on Saturday and the Marathon is on Sunday. This will make the crazy early morning parking much worse than normal.
Ruxton will be blocked off for the starts. The Ascent has 2 waves with the first at 7 AM and the second at 7:30 AM. The marathon has a single start at 7 AM. Obviously coming back down Barr Trail when hundreds of runners are going up would not be a smart choice..
