Previously a very tough and hilly half marathon, the Mansfield Half Marathon has now rerouted itself a little to ease the strain.
The three forts in question are the magnificent iron age hilltop camps of Cissbury, Chanctonbury Ring and Devil’s Dyke on the South Downs
The marathon runs along a historic route through the Wiltshire and Hampshire countryside – the Clarendon Way
The Eastbourne Half Marathon follows a route which is mainly flat with a hilly section early in proceedings.
