About 100km.com

How It Works

100km.com was designed by athletes like yourself to find the fastest human beings amongst us. At the moment we are focusing on two main areas, running and cycling. Our leaderboards allow any of you that have completed the required distances for each event to upload your times/stats to our leaderboard.

For cycling we have set up 50km and 100km race,and running 100km, 50km and 21.1km. Using Strava integration for your ride or run, your data appears and you can see how you rank among the fastest people locally, or on the planet. 

In order to keep things fair we calculate the elevation of the entire distance to calculate whether it was downhill; and it will appear as “downhill” if there’s more than the specified metres of decent between the start and finish points:

  • 100km run: 1500m
  • 50km run: 1000m
  • 21.1 km run: 500m
  • 100km ride: 1500m
  • 40km ride: 900m


To keep the leaderboards in order we rely on strava and as athletes it’s an honour system. Power meters on bikes, as well as a heart rate monitors for all your efforts, are the very best way to validate any ranking.

FAQs

  • How do I record a run/ride on 100km.com?

    Make sure you’ve linked to 100km.com with the ‘register now’ button and enter your information. This will link your strava account to 100km.com, then just use strava as normal, all efforts that include our distances will be uploaded.

    In order to upload data from a run or ride completed prior to registration, you will need to do this manually. This can be found under ‘submit activities’; select the month and year you completed the run/ride and hit ‘find activities.’

  • How does 100km.com decide where my effort starts and finishes ?

    We calculate the fastest part of your ride over the distance; if you ride 120km we take the fastest part of that ride that applies; if it’s a run the same system applies. 

    You can ride or run 100km and the fastest 100km of that ride or run will go on our leaderboards.

  • What if I’m in a group does it count?

    We don’t differentiate between solo or group rides (or runs) right now; you can put SOLO at the start of the ride name if you want

  • What if I’m over the set descent in a ride or run?

    Your ride or run will automatically appear in the “downhill” category if your decent is more than (calculated as the difference between the start and finish points):

    • 100km run: 1500m
    • 50km run: 1000m
    • 21.1 km run: 500m
    • 100km ride: 1500m
    • 40km ride: 900m
  • What if I want to “flag” a ride or run will you remove it?

    You can email us and we will try to have a look. 100km.com is an honour system at heart, we don’t want to see abuse in the first place.

  • What if my ride is wind assisted does it count?

    We can’t tell so it will appear. A look at both power and heart rate data will tell the story usually. For a ride to be truly credible add both those data fields; if you had a tailwind for a 100km ride ... you got lucky!
