Off road I don’t enjoy at all – a mid ride pint makes the next hill massively hard work. A pint of shandy is about as much as I can manage.
On road in London I seem to be good for about 2 pints feels fine. 3 a bit interesting though the exertion seems to do a good job of sobering me up. More than that gets a interesting in a bad way. Riding a regular commute like this is on auto pilot – you know all the danger areas and ride defensively through them.
It kind of feels the same as helmets and riding off road generally – the chance of hurting anyone but myself is negligible. Driving a car after any more than a pint and a half I consider a complete no-no for the opposite reason – I’m more likely to hurt someone else than I am myself.
An unknown route is a bit different. 6 pints one night in West London should have seen my home to Brixton in 45 minutes or so (it wasn’t that far from my normal route). 45 minutes later I was 1km west of where I’d started. Still don’t know how.
