Our One Slam virtual event is back for the sixth time in 2026, once again encompassing Christmas week to give everyone a running head start into the new year.

The event takes place over a 10 week/ 70 day period: 25th December 2025 - 5th March 2026. Runners have a choice of distances that they can aim to complete within that time. The option to step up to the next level, or down if it becomes too much - is there at any time, just keep going! The event is for everybody, anywhere in the world. The targets are as follows:

  • 50 Miles (5 miles per week)
  • 100 Miles (10 miles per week)
  • 200 Miles (20 miles per week/ The equivalent of the 50 Mile Grand Slam)
  • 300 Miles (30 miles per week)
  • 400 Miles (40 miles per week/ The equivalent of our 100 Mile Grand Slam)
  • 500 Miles (50 miles per week)
  • 600 Miles (60 miles per week/ The equivalent of our Double Slam)
  • 1000 Miles (100 miles per week)

Part of the One Slam focus is helping our Centurion runners start the year on the front foot, but not just by encouraging consistent training, but also good opportunities to learn as well. As part of your One Slam entry you will have access to fortnightly webinars from our coaching team, on subjects such as training, nutrition, kit, racing and more. As well as open time for questions after each.
