You'll be fine. You haven't lost any fitness in two weeks, provided you haven't been sick or anything. Think of it as a taper. You're fit and you'll be well rested for the ride.

I've found the NWS's hourly weather graph to be very accurate a couple of days out. It's a little bit early to check for the weekend yet, but here's what they're saying for Brainerd as of now - nearly 60° by 9 a.m., partly cloudy, humidity and winds nice and low. Sounds like a perfect day for a ride to me. http://forecast.weather.gov/MapClick...2&AheadDay.y=7 Have fun!
