Some clubmates and I did about 50 miles in nice weather (sunny and ~50F): http://app.strava.com/rides/4800113 There's one categorized climb on that route, plus lots of rollers and moderate winds. I rode the climb fairly well, and had the sport-touring bike instead of the mountain bike, so I moved up the leaderboard from 7th to 2nd.

We had to moderate our pace for one rider who doesn't have his springtime legs yet. In the end, I had the most endurance and got extra time on the front, which was great What doesn't kill you, totally justifies eating as much as you want afterwards, right...? So a great ride in our best weather this year. 18.6mph moving average, 2300ft ascent, 51 miles.
