I'm new to cycling & would like any advice on getting into the sport. FYI, I'm a 44 yr. old woman, mother of 5, riding a cheap Giant Mnt. Bike. I'm on week 2 of a training schedule I found online, few offered. I did 35 m. last week while my goal was only 27 m., according to the schedule. My intention is to log 500 m. on my crap bike & the buy a new Trek road bike. I just want to be sure I'm committed before I drop any more money into it. So far I've bought a water cage, bottle, computer/odometer & bike-mounted pump & had to buy 1 new tube. I'm hoping to buy the Trek by September.
