Stage 2: sealed road, greenway, steep track
At the upper part of the hill, the terrain changes to sealed road and then joins the old railway track greenway. At the end of the greenway track, it’s time to ascend Howth Hill again and make it to the summit.
Stage 3: Field run
The route then follows the trail back down the hill towards the finish line at Deer Park Golf Club.
The route varies from sealed roads, wet bog, forest trails and gravel paths. Expect the unexpected!
