Course format

Park 12 hour built for rhythm

This looks more like a settle-in road race than a course that wins by terrain alone.

Elevation profile

0 ft net

3 ft up and 3 ft down across the 12 Hour. Net flat overall.

Pressure point

Crowded opening miles

Getting clear road early can matter as much as fitness, so wave position and patience both shape the outcome.

Weather bias

Weather can swing fast

Cooler starts, sun exposure, and mountain-weather shifts can all matter more than one average forecast line.
