  • Zero Elevation Loss

    To stop people running down a hill to get a good time, we require people to evidence zero elevation loss during their attempt. You can do this by either running a flat course, or, by ending the same spot in which you started. This can be achieved by running a looped route.

  • Set treadmill gradient to 2.5%

    It is preferred that you attempt this challenge outside, however, if you are unable to do so and must use a treadmill, the gradient of the treadmill must be set at 2.5%.


  • Utilise the 'Lap' button on your fitness tracker

    This will help you keep track of your times during the challenge. Alternatively, some fitness trackers allow you to create a workout within the app, to better track your performance.


  • Screenshot of fitness tracker lap times

    Take screenshots of your activities for upload.

    Some trackers you could use are Strava, Garmin or Nike Run.


Before submitting, please make sure you have your evidence ready. Submit evidence for all of the challenges in the same challenge series by the deadline below to earn your Finishers Pip.
