I started riding seriously about 4 weeks ago. I have doing about 80 to 90 miles a week, doing 25 miles and last weekend a 34 miler. Yesterday I did a 41 miler with two 12% climbs and several other hills. I averaged 15.3 mph, being able to ride about 19 to 20 mph on the flats, with several climbs that lower the average speed. I am getting ready for a 57 miler on my 57th birthday, November 29. I have a 12% climb two miles into the ride and the same 12% coming up the back side at the end of the ride. Pretty excited about the progress I am making and loosing some weight in the process, 207 down to 196. I have a ways to go yet, but it is enjoyable and I am getting stronger. Anyone out there have an tips for training for this? I am riding solo as there don't seem to be any roadies in my area.
