Hit Lidls and bought some 'sports' glasses with 3 lenses (£4), running top (£5), Heartrate monitor watch (£13) and some stretchy bandages.
Glasses look alright, although no ventilation at the top. Top's quite thin, but will do for summer jogging and biking and watch has a pretty crappy interface, but will do nicely for 13 quid - Much more features than my £50 quid Polar, including lap timing and replacable battery in the heart strap. Quite happy.
Also put some slicks on the Rockhopper, doesn't look quite as undertyred as I thought it would.
