The Las Vegas Marathon – Sunday 4th December

Billed as the world’s largest nighttime running event the 2011 Rock ‘n’ Roll Las Vegas Marathon starts in the fading light of late afternoon and ends in the glow of neon lights up and down the Strip. Whether you’re a serious athlete or planning on dressing up as Elvis (you’ll certainly be among friends if you do) you’ll need to be pretty fit. The roads are re-opened after just 4hrs 30mins so if you’re a back-of-the-pack plodder, beware!
