I gave into temptation last weekend and bought a run-out model Boardman
Team TT bike for my triathlons.

I've ridden it once, but didn't feel comfortable on it - since them I've
made some adjustments (moved the saddle back, flipped the stem and
adjusted the width of the aero extensions) and had a little ride up and
down the road - feels a lot more comfortable.

But... how long should it take to truly feel in control of one?

I have a sprint duathlon at Castle Combe racetrack next weekend - an
ideal place for my first race on it - but I'm really concerned I'll not
be confident enough to ride around other riders.

I could revert to my road bike - but this thing feels like it's worth a
good couple of minutes over the 10 mile bike segment.
