For various reasons (including taking on a second job)I've not been cycling properly since before Christmas. Since then I've built up a new bike along similar lines to my old machine for a mix of on and off road riding. I picked some different tyres for this build and thought I'd try some Schwalbe Marathon Extremes as they look like they might be a good on/off road option. Now the Extremes are a bit heavier than I'm used to, my previous 2 sets of semi-slicks have been in the 530-550g range, the Extreme's quoted weight is 570g, which doesn't seem too over the odds (although on my scales they come out around 630g!!) and Schwalbe go on about how fast rolling they are, so I thought that they'd be worth a go.
The thing is it feels like I'm cycling through treacle at the moment, it could be the the heavier tyres and/or the different compound but then again I've been off the bike for 5 months plus so I'm not exactly at the top of my game fitnesswise. I'm not a racer so optimum acceleration isn't a priority but I do like a good climb and I don't want a tyre that's going to sap energy excessively.
How long should I give my fitness to get back to where it was before deciding to ditch the tyres or not? A couple of rides seems a bit premature but I don't want to end up spoiling my enjoyment of cycling either.
