g'day,
i don't think anything can replace the thrill of a 'bunch' race, be it crit or RR. As i mentioned in the 'crit thread', you'd be crazy to compromise your health & safety in 'bunch' racing, if you can't afford to take a fall (& it sounds like you can't!). ITT's are great though, TTT's are enormous fun too. As was mentioned,it's you against the
clock, no excuses, no 'sitting on'. This sounds like the ideal competition for your situation. I've done probably 50, i guess. PM me if you'd like some further TT tips or info,
cheers,
Hitchy
