Thanks for all the tips everyone. Early mornings are what I'm doing now, I have to be back by 7.20am to get the kids up for school. However Hubby moans that I wake him up. Not sure what I can do about that as I get dressed etc downstairs to make as little noise as possible and I don't eat etc. just up get dressed and run! Ah well it will work out.
Fortune favoured me with a little extra money this month, which I took as a sign so I entered!
I still intend to ride my 23 year old road bike for this though, it is off for a respray soon. Friction gears are the way to go 
Wetsuit required and I feel I may need to upgrade the bike a from toe clips to clipless peddles.
SD Not sure I dare fess up to Tri-Anglia what I've done. It's really muppetry of the highest order!
