...By the way, the Bryan Chapman ain't that hard, so if you're living in S Wales, then you really should ride it.
What makes it such a special event - apart from the route - is how well you are looked after, and the size of the field. So you get chivvied along by fellow riders on the road, and you waste little time trying to explain audax to the civilian populace, as it's merely a matter of getting to the control. If you live close to Chepstow, it's a no-brainer.
Riding twice across Wales also gives it a simple narrative, which appeals to me.
