About
Windward Half Marathon and 5K is held in Kailua, Hawaii, on March 21, 2027, and starts very early: the half marathon (13.1 miles) sets off at 6:00 a.m. and the 5K five minutes later at 6:05 a.m. Two distances, one morning, and both are done before most of the day heats up.
Those dawn start times are worth planning for. Do some of your long runs at the same hour so your body is used to running early, and rehearse breakfast and hydration on those mornings too. The 5K works as a hard, short effort or an easy warm-up to the weekend, while the half rewards a 12-week build with a weekly long run reaching 11 or 12 miles. Runners coming from the mainland should give themselves a few days to adjust before racing.
