Thanks for all the feedback which gave me the encouragement to accept the challenge BUT then the better half had delight informing me it was on the same day as the U2 concert at Twickenham I'm going to, so thats the end of that challenge.Hi there. Yes I did it last year, it's a great Sportive. I am assuming it is the one that starts and finishes in Cardiff, and takes in the Tumble and Caerphilly Mountain? These are the two main climbs, but the rest is pretty tame. The first 50km are pretty much pancake flat and perfect for warming up the legs and getting a bunch of distance behind you. Do it I say, I loved it. There is always someone to tuck in behind.
Now that I'm up for a challenge is there any other organised rides you have done(100 miles) that you would recommend doing.
