Ds (age 11 and one day), my dad and I enjoyed the Pedal for Scotland. Ds and I probably did about 52 miles by the time you've added on the cycle to and from Glasgow Green. Took us about 6.5 hours but that included stopping at every rest stop (every c.10 miles) and dad stopping to help someone who needed a spanner to deal with a puncture.
There were loads of punctures - must have seen hundreds of people stopped before we'd even left Glasgow. I know with c8.5,000 people doing it, there will be a fair few punctures, but there seemed lots. We were fortunate and dind't get one on the ride itself, although ds got his first ever puncture on the way to Glasgow Green, so my dad had to do a rapid repair job once we'd met him (fortunately we were within bike pushing distance).
Also saw at least 3 blue light incidents/attending - and know of one death as a friend's dad who is a doctor was doing it and he apparently had a 2 hour detour to A&E after resuscitating someone but they didn't make it. Salutory lesson on why you should fill in the details on the back of the number though: the guy had no ID on him, so it took time to get contact details. :(
The finish through Muarrayfield stadium was a nice touch.
Ds coped admirably - still needs to learn to cycle at a more consistent speed as he's a nightmare to cycle behind but he says he suffered no ill effects, even the following day when he got back on his bike to go to school but then he did spend most of his time up out of his saddle
My training must have been adequate too as my bum wasn't too sore the following day either!
All three of us zonked out on the bus on the way back to Glasgow - but getting back on the bike for the last 2 miles wasn't too bad. The weather was crap back in Glasgow and had apparently been bad for the Sky Ride - but it had been OK for us throughout our ride. I suspect we were just ahead of the bad weather all the way - and got the benefit of a tail wind.
Ds is desperate for the Islabikes Luath drop handlebar bike. I've told him he is between sizes at the moment so there's no point getting one. We will probably end up getting one for him for Christmas.
In truth both dh and I "need" new bikes before ds does (he's got a good Islabike Beinn at the moment) but....... he does get such pleasure from his cycling!
