Shifting Riding Styles

I rode 48 miles today from Portsmouth down to Exeter, over to Epping and Newcastle and back up again on the Specialized Langster I assembled last year. That bike climbs incredibly well with the combination of a stiff frame and low weight. But it akes me miss light geared bikes. The fixed gear had me feeling held back, reserved. I wanted to accelerate and keep speeds higher than I was willing to continuously pedal. And climbing later in the ride, like around mile 35 or so, became manageable but more restrictive on the fixed gear. Here's the LINK to the GMaps Pedometer map w/ elevation chart..
So I suppose my riding style might be shifting back to the more traditional geared cycling, trying to bring back some speed that I've let go of the past 4 years or so.
