After a discussion with the fitness instructor at work and a re-evaluation of my current training regime i've put together a more structured plan for the next 5 weeks. I'm trying to mix it between distance/endurance and speed training so a week now consists of:
Monday - 12mile speed training route
Tuesday - 20mile+ distance ride
Wednesday - 1hour hill training (gym)
Thursday - rest day
Friday - 12mile speed training route
Saturday - 50mile+ long distance ride
Sunday - rest day
We'll see how it goes!
On another note, I've decided after Saturdays ride that I'm going to take the plunge and purchase of some proper cycling shoes, clip in peddles and cleats. Looking at the dhb R1 road shoe - not exactly top of the range but very reasonably priced entry level and highly recommended. Will order asap.
