Starting at 65°F, heat will be a factor from the gun — go out conservative and stay on top of hydration. Moderate winds around 13mph may affect pacing on open sections of the course. Moderate humidity at 71% is worth noting for effort level, especially in later miles.

About the Georgina Half Marathon

The Georgina Half Marathon is a single out-and-back along Lake Drive on the south shore of Lake Simcoe, starting and finishing at De La Salle Park in Jacksons Point. The Athletics Canada certified course is pancake flat, with an elevation profile that varies by only a few metres, and it runs on a quiet cottage road with plenty of shade and views of the lake. It is the same loop the marathon runs twice, and it starts alongside the marathon on Sunday of race weekend.
