I live in Swansea and have ridden those hills many many times, the Dragon is a real spectacle, love seeing all those bikes especially those first two climbs. Don't gun it to hard on those as it easy to carried away, there's a fair bit to do after but its not an arduous ride after Rhigos Mountain, the medio is just a nice easy ride all round really. As always cycling is a great excuse for eating lots but the feed stations are very busy so take a little extra food with you. Take care on the descents, especially in the wet, they are very fast indeed, you can reach 60-70kmh without even trying.
Hi Sketty, thanks for the advice. I've read how bad the stations are and cant believe there are only two on this route. Looking forward to the ride, hopefully it will be a sunny day!
