I did Turin in 2000, and then done London for the first time 2 weeks later, 3.24, followed by a 3.28....
Turin was excellent and i can certainly recommend it, about 3000 runners, fairly flatish, one hill before halfway i think, some nice countryside, and a finish through the city!
Ryanair flys there from Stansted for cheap flights, paid about 35 quid i think at the time. Reasonable cost of hotels, and on-line entries, i really enjoyed it!
The only downsides i can remember, are Sparkiling water or Pure orange juice at stations...and KM markers instead of miles, which caught me out!
But overall this is the only overseas one i have done, and was great!
May consider again, when i get my annual rejection (2000 was my only success out of 9 attempts!)
