Overview
The Maldon M100 took runners through Maldon, United Kingdom, across a 163-kilometer course packing 39.7 meters of climbing into every kilometer. Accumulating 6470 meters of ascent over that distance meant relentless uphill work with few sustained flat stretches to recover or build momentum.
With a 32-hour time limit, participants had to hold an overall pace of at least 11.8 minutes per kilometer, including all aid-station stops. That cut-off was tighter than 55% of 100mi races and more generous than 45% of 44 peers, leaving runners who fell off pace facing elimination on the climbs. Organized by Top Day Events for an entry fee of £120, the event demanded constant forward urgency to stay ahead of the sweeps.
