I ran round the lake 6 weeks ago. Loved it. Just ran my first half on Sunday (Stafford) in 1:34. Hope to run this one in sub 1:30. Tea and cake at lakeside view probably a bad idea!
Vyrnwy is quick, although you can have a tendancy to go off like a nutter on the first 5 mile... which you have to keep the reigns on. When you make the turn, think this is around 7 mile, then there ARE inclines, nothing serious but if you'r eon your limit, you will pay... however, you have to take the option that at 12 mile, the l;ast mile is fast... so treat it as a 12 mile race... and you'll be fine.
I'm hoping for something rather tasty here BUT with Berlin Marathon 1 weeks later, may have to old back... I'll see how I feel closer to the time.
