The Gnarly Greenway Loop came about after many, many (!), trips around the Letchworth Greenway, honing and refining it to create a few detours along the way to include some more interesting sections to spice things up.
At just 16 miles it still offers a great variety of trail types from the cinder track that is the Greenway, to potholed farm lanes and open countryside.
Ridden at a decent pace, the Gnarly Greenway route offers the opportunity got a great workout in any weather conditions.
