Here’s a quick need-to-know primer about today’s 41-mile ride from Okoboji to Emmetsburg:

WEATHER: Mostly sunny skies will heat up Monday, says meteorologist Ed Wilson of WHO-HD in Des Moines. The early morning temperatures will be in the lower 70s. The warmer air will also help to push highs to the upper 80s by the afternoon. It will be sticky with higher humidity, making it feel like it’s in the middle to upper 90s, or even 100. The south wind will continue to be breezy in the afternoon. Gusts could reach 25 mph.
