Hell thats a pretty tight schedule. Why? Sounds like confusion, are those times right Seren? transition opens at 5:30, but you cant register till 6, then you've only got 15 minutes to get all racers registered and the last guys only get 15 minutes before transition closes. Then its 30 minutes before the race starts.
And remember you guys are parked up by the golf course, no parking down by the visitor centre.
Looks like the route has been changed back to the 'old' road avoiding HOV A465 all the way. I live alongside it & the only sections I've ever ridden are the uphill from Clydoch to Brynmawr for our club hill climb champs and the bit from Clydoch to Gilwern. Wouldn't normally consider riding the sections they had incorporated into the race, even without the road works.
