I'm 26 years old, 5'8 210 lbs. I started dieting last month and lost 15 lbs since. I finally got back on the bike today (haven't really biked for 2 years) and did a 10 mile ride. I was sweating, huffing and puffing, etc.
I know I'm out of shape, but my area is all flat and I was barely able to keep 11mph, varying depending on wind direction. I'm working on losing weight and want to improve my biking so I can be competitive next year. How can I get to 15-20mph consistently and 25-150 miles?
My plan is to do 3-4 rides for a week or two for 10 miles then try to progress each week. I'm really concerned about my speed though, not sure how to improve it.
