I would like to start training to do a 100 mile (century) ride. I am biking on an exercise bike right now. I live in NH and its early march, so yea, I won't be on my road bike for 4 weeks or so. But when in I do get on it, I would like to do 100 to 150 miles a week at a good speed and including a fair amount of hills. This is assuming the weather permits. I'm sure some weeks I won't be able to bike more that 30 or 40 miles due to weather. But assuming I can keep my goal of 100 to 150 miles a week of morderate to intense training, how long would you think before it would be before I could do a century ride? I could easily do 40 miles or so at a time last season so im sure I will get back to that point in no time this spring. Oh, and as far as my daily length of my rides goes: during the week I would like to do my 11 miles route that includes 2.5 to 3 miles of uphill riding. I will do more if I have time. During the week I will probably max out at 25 miles a day, but most days, I'll be doing my 11 mile route. On the weekends I would do anywhere from 25 to 45 miles of various difficulty. And obviously slowly i will bump up all of my routes so i can gain endurance. After a few weeks I will try to get 17 miles during the week a day and then get up to 60 miles on the weekend per ride. And so fourth. Thanks for the help!
