When I ride with friends I tend to be at the back of the pack and often get dropped on the slight inclines that are called hills on Perth's coastal plain.
I want to raise my level of fitness to keep up with those friends at least, and it would be nice to climb much better.
I have a HR monitor and understand HR zones. I have also recently purchased a nice trainer (TACX fortius) so I can ride at night
So where do I start?
