Spring: last time to enjoy the snow before next winter, and in Ashton Court, last time to enjoy the mud before the summer rains return. It's not ideal though.
It's warm and dry enough that a lot of people are coming out, out without mud tyres, instead bringing all-round MTB tyres and the optimistic belief that they can get round without getting covered in mud.
These spring mountain bikers are trying to get round the course mud free, here skirting round the deep puddles.
This is widening the trail. It was tighter during the deep winter mud season; all these people trying to stay clean are downgrading the area. They should embrace mud and set their bike up for Bristol, not dryer places like Wales.
