Comfortable temps

Starting at 63°F, heat will be a factor from the gun — go out conservative and stay on top of hydration. Light winds shouldn't be a major factor for pacing. Moderate humidity at 69% is worth noting for effort level, especially in later miles.

Race Info

The 10 for Grete run covers 10 kilometers through central Oslo, starting and finishing at Radhusplassen. It's named for Grete Waitz, the Norwegian long-distance running great who co-founded the cancer charity Active Against Cancer; the 10K was renamed in her honor in 2011, the year she died of cancer. It's the shortest of the Oslo Marathon's competitive running distances, drawing runners from elite level to first-timers.
