A flat, even-effort course where steady goal pace is the whole game. The deep shade keeps temperatures down, so you can run honest splits start to finish. Just don’t get so lost in the scenery that you drift off pace.
Pacing by goal time
Checkpoint splits for four common goals at Avenue of the Giants Marathon. These are effort-even rather than pace-even: the paces shift with the course profile, so climbs are slower and descents faster by the amount the grade actually costs. For any other goal time, use the planner below.

Grade adjustment is a model, not a promise. It assumes even effort and ignores wind, heat, and how well your legs handle sustained descent — which on a steep course is often the deciding factor.

Fueling & hydration
Aid stations appear roughly every 2 miles with water and sports drink along the out-and-back. The level rhythm and cool canopy make a fixed gel schedule easy to keep; the shade keeps fluid needs modest but steady.
Weather
Mid-May in the Humboldt redwoods is cool and often damp (40s–50s°F), with the dense canopy holding morning mist, making for fast, comfortable racing weather beneath the trees.
Is Avenue of the Giants Marathon a good Boston qualifier?
Yes. The course drops 2 ft net, comfortably inside the 1,500 ft threshold where Boston's downhill adjustment begins, so a time here is submitted as run.
This drop is our estimate rather than a figure from the course's certificate. If it sits near a threshold, confirm with the organizer.
