It’s December, it’s a bright frosty Saturday morning and it’s time for the Mouth to Mouth Marathon.

This is the last Sussex Trail Events race of the year, the inaugural Mouth to Mouth race and the 4th and final in the river marathon series for 2016.

The concept and the route are pretty simple. 6 flat kilomemtres up the river Adur from Shoreham by Sea, a 7.5km climb up to the top of the South Downs, a 4km descent back down, a 2.5km climb back up, 5.5km of undulations on the South Downs Way, a 3.5km descent to join the river Adur, then all the way to Littlehampton Marina following the river via Arundel on the flat.
