Course format

Trail race with mixed terrain

Surface, footing, and terrain changes are likely to matter more than one exact split-by-split route line.

Elevation profile

Mixed terrain profile

Footing and climbing matter here more than one exact elevation number, so plan for effort swings.

Pressure point

Altitude adjustment

Even a modest rise can feel bigger if you are not acclimated, so keep the early effort calmer than sea-level pace.

Weather bias

Usually weather-dragged

Typical starts are around 67F, so even manageable mornings can still get more expensive later.
