ZD30 The Summit (1 Mile, 5K, and 10K, 1/2 Marathon, 30 Mile Ultra)

ZD30 The Summit takes place in Boise, Idaho, on November 7, 2026, with every distance starting at 10 a.m. The lineup runs from a one-mile run/walk through a 5K, a 10K, a half marathon (13.1 miles) and a 30-mile ultra, so a whole family or running group can enter the same event at very different efforts.

If you have already finished a marathon and want to see what sits beyond it, the 30-miler is the reason to circle this date. Treat your final long runs as time on feet rather than pace work, and rehearse your fueling exactly as you intend to use it on the day. The half marathon stands on its own as a late-season target, and a 16-week build with one long run each week gets most runners there comfortably. A 10 a.m. gun is later than most road races, which leaves room for a real breakfast and an unhurried warm-up.
