Hi,
Thanks Gravitas and & 3abdu… I do indeed have the Schwalbe Marathons, but not the plus. I’ve not had anything on the front tyre yet but I think it might have been possibly a gash from one of the larger stones used in the most recent re-gravelling. If I have any more I’m going to consider upgrading to some of the heavier duty/more agressive tyres from Schwalbe for the winter -I have a gravel/adventure bike so plenty of clearance. My old MTB never had a puncture for years on this route (at least until puncture alley at the back of Harwell was put in place with those darn flint chips they used for a dressing!).
Thanks,
Steve
