I bought a replacement track pump after the old one exploded a few months ago, and after I got home last night decided to pump up both tyres as they seemed a bit on the squeeze side. They were around 15psi!! So pumped up to 40 now, see if that makes a difference. Still using my old (very well worn) tyres, got a pair of new ones waiting to go on but making the most of the old ones in the meantime. Will need to get a better quality pump for carrying with me as my Tesco one just isn't up to much.

Did 21km last night despite stopping when I happened across a gorse fire, first time I've ever had to call 999
