The next edition is expected on Sunday 19 September 2027, following the pattern of previous editions (the 3rd Sunday of September). The organisers have not confirmed it yet. The course is run on road surface with 272m of total climbing, with its high point near 1548m above sea level. For registration and full race details, visit the official Waterfall City Half Marathon website.
Climbing
At 272m of total climbing, it is hillier than 88% of the 634 half marathons we rate. The hills will cost time: pace the climbs on effort, not on the watch. It runs at altitude (up to about 1548m), where thinner air slows most runners who live near sea level.
Race-day weather
Over the last 4 years this September date has averaged a high of 27°C and a low of 13°C. That is warmer than 89% of the half marathons we track. On our model the expected temperature costs a 1:30 half marathoner about 3 minutes against the same course on a cool 12°C day.
On 19 September over the last 4 years, the high ranged from 22°C (2026) to 30°C (2019), so pack for either. It stayed dry on all of them.
