Thanks, to everyone for the posts. Sounds like am just over-worrying and am sure once I get a bit more used to the bike and do some more long runs on lots of hills I should be okay - will just need to keep pushing up the hills till the top.
Oh, aero bars are another issue altogether - borrowed from a friend but if am honest I don't really like them and plan on not using on my new bike.
