You have a decent road bike don't you and are reasonably small/light? Would probably suggest Road Racing in that case, as you don't need to buy a load of aero-bongo / new bike...
In which case I would look at training for fairly short efforts (couple of mins) and increasing you ability to quickly recover from those efforts, given that we don't tend to have long 10min+ climbs in many of the road races in this country.
I am trying to reverse engineer an answer to that ..
I have been presented the gift of redundancy and the gardening leave begins next week; I promised myself I'll get better by doing some off bike work during this time but if the sun is shining that can fuck off. So I need a purpose. Otherwise I'll just gram #slackermiles
