The Source to Sea Trail is an adventure by gravel bike or mountain bike into the heart of Yorkshire. It is a circular route, 730kms long with 9,000 metres of climbing, that connects the network of old tracks in the folds of the hills and on the moors where 10 of Yorkshires finest rivers rise.

The 3rd Source to Sea Trail event will be held on 23rd - 28th May 2026 with the start line once again at Mytholmroyd Community Centre in the Calder Valley, West Yorkshire and a group start at 8am.

This is the only bikepacking route in the world to trace the watershed - the high ground - of a single large scale river basin (Humber).

Entry to the Source to sea trail: 3rd edition

The trail connects bridleways across the Yorkshire Dales, North York Moors, the northern edge of the Peak District and the South Pennines. The trail is 70% 'off-road' with farmers double track across millstone grit, singletrack across limestone and greenways on canal towpaths and reclaimed railway lines.

It is the only bikepacking trail in the world that traces the watershed - the ridge of high ground - of a single large scale basin where rivers such as the Aire, Calder, Derwent, Esk, Nidd, Swale, Wharf, Ure and Don have their source and follows their flow to the sea.

Entry to the 3rd edition opens 3rd October

Anna Cipullo shares her experience of the second StS event. It was Anna’s first bikepacking event and with plenty of amazing shots of the Yorkshire landscape alongside Anna’s highs and lows over the 730km route this is an excellent insight into facing the demands of long distance ‘rough stuff’ riding.
