Join us for the UK's biggest running event 26/27 May 2012 - the Edinburgh Marathon Festival.

Choose between the full marathon, the half marathon, the 10km or the 5km. The full marathon is the fastest in the UK so only for the fittest.

Better still make up a team of four to cover the 26.2 miles between you for the relay:

Leg 1: The Royal Leg - 8 miles

Leg 2: The Cock & Pan Leg - 5.5 miles

Leg 3: The Gosford Leg - 8.2 miles

Leg 4: The Glory Leg - 4.5 miles

When you enter the relay, you can choose between seven different categories ranging from Fancy Dress to Auld Reekie (average age 45!). The first three teams over the line and the winning team in each of the seven categories will win a prize!
