esther, you are doing well! regardless of age you say you're only gotten back into cycling a month ago and you're doing 10 miles at a good clip?

keep it up, most important keep it fun, don't neglect the whole rest, recovery & nutrition thang. You'll do your 25 and more if you want.

Cycling is a multi-year sport building up a base and endless cycles of training and rest.

So keep it fun! I'm 50, started back in about 10 years ago and this year plan to do my 3rd 585 mile (in 7 days, not one day ) CA AIDS ride.
