To be honest, Afan isn't that mountain-y. The hills are at the start, so once you cough up the first lung, the rest is not so bad
Really just a few fireroads and man made (read smooth) singletrack.
Great techy (windy, not rocky) downhills though.
Always rains though...
Oh, also, if you don't like big drops (not riding off, they are fine
) avoid the wall trail, think cliff, with off camber ledge into side. nice
afan is pretty tame by welsh standards. has to cope with a real mixed skills bag of riders so not real technical. the old (early 90s) XC course had considerably harder climbs than curently used. so yeh, in this instance ideal retrobike meet
right about the rain tho, only ridden there once in the dry (yetitribe this summer gone)
happy to show you guys around my local trails. I live within 4miles of 2 previous UPS DH courses, should be fun on fully rigid retro
