Overview

The Pierewaai Summer Beach Trail in IJmuiden is a 60-kilometer trail race with 600 meters of elevation gain. This gives it 10 meters of climb per kilometer, making it steeper than many other 50k races.

With an 8-hour time limit, the race has a tighter cutoff than 97% of its 50k peers. Runners must maintain a pace faster than 8 minutes per kilometer to finish within the allotted time. The field size is smaller than 31% of 2650 comparable 50k races.
