Summit Run 5K

Runners will face a temperature progression from 59°F at the start to 63°F at the finish, with a light wind peaking at 7 mph. A notable 680ft climb between miles 2 and 3 will be challenging, especially with a headwind during that segment. It’s advisable to start conservatively and adjust pace as needed, particularly in the hilly sections and where winds shift.
