For example my work schedule means I only get to do one long run each week in addition to a bunch of short ones. The big difference is as time goes on I can increase the long on. So say I do 3 x 3 miles midweeek, and then 5 miles at the weekend. The next week I can up that to 3 x 3 miles midweek and 7 at the weekend, then 9, 11, 13, etc. It's all about building up rather than taking one huge leap at a time.
It's remarkable how quickly the body adapts.
