I can’t confirm whether or not it was me at the moment as without checking I’m not sure where I was on the 25th. Did you have to leave it so long before asking – I thought even North Wales had internet access nowadays?
Though come to think of it, are you sure it was a bike not a unicycle? I mostly ride a unicycle off-road nowadays, so if it really was a bike, then I guess that makes it unlikely it was me.
Actually pondering that again I’ve never ridden or pushed my unicycle up or down Snowdon, so the fact it was a bike you saw actually makes it more likely it was me. What colour did you say the bike was again?
