My Better 5K race day weather
Cold start — layer up, chance of rain
Runners will start in chilly 38°F conditions — dress in layers for the corral and plan to shed early. Light winds shouldn't be a major factor for pacing. There's a chance of rain, so have a backup gear plan ready. Moderate humidity at 78% is worth noting for effort level, especially in later miles.

About the My Better 5K
The 5K is 3.1 miles from Seward Park, on the shore of Lake Washington in south Seattle. A steep but quick hill comes right at the start, and once runners are back down the rest of the course is easy. It starts at 8:10 AM, after the half marathon and the 10K.
