Run Britain Rankings
Runbritain's revolutionary handicap scoring system is designed to give runners of all abilities the ability to benchmark their progress and compare their results across a range of distances and terrains.
They include road, multi-terrain, track, cross country and trail races so now nearly all events that are licensed by UKA/runbritain can contribute to your handicap. The algorithm they use allows a direct comparison of the current form of different runners to be made. It does not matter if the races if you do were in tough, moderate or fast conditions as the algorithm asesseses the difficulty of the course on the day so that you have as good a chance of improving your handicap on a hilly course on a tough day to a flat course on a calm day.
