From 1 Jan 2022 to 10 Apr 2022


Our One Slam virtual event is back for 2022. We've made a few changes and added a few things along the way, but the main aim remains the same. To bring our community from all over the world together virtually once again. As ONE! 

The event which takes place over a 100 day period: 1st January - 10th April 2022. Runners have five distances that they can aim to complete within that time. The option to step up to the next level is there at any time, just keep going! The event is for everybody, anywhere in the world. The five targets are as follows:

100 Miles
200 Miles
400 Miles
600 Miles
1000 Miles

We are also incorporating five additional challenges within the longer term goal of your chosen distance. These draw upon all of the different virtual events we held over 2020 and 2021.

Entry to each of these is optional and included within the overall entry fee. These are explained in more detail below:

General Info

What is It 

The challenges are once again based around our traditional Grand Slams - spanning a time frame of 100 Days. Runners will have between January 1st 2022 and April 10th 2022 to take on either the equivalent of the 50 mile Grand Slam - 200 Miles, the 100 Mile Grand Slam - 400 Miles, or the Double Slam - 600 Miles. We have also kept the 100 mile challenge. Kids can enter and compete on bike or scooter if they want. We have also added a stretch goal of 1000 miles too. 

You can also register for the canicross event - Simply select 'yes' during registration to 'running with a dog?' and you will appear in your age group but also the canicross category (medals are not provided for our canine friends but you can give them your one!).

All you have to do is run whenever and wherever you like, then submit your distance to the database. You can do this automatically, by syncing your entry with strava or by just manually entering how far you ran, each time you do so. The system will then calculate your total distance and update both the results table and your position on our virtual map. It will add together your cumulative run distance only. 

The submit results page is now live here.

If you are a strava user, you can link directly to strava and the results table will automatically update for you. No more manual uploads!

The results for each event will show in order of cumulative distance only. Remember this is not a race, the primary objective is to complete the challenge you set for yourself and to engage with your friends, family and the Centurion Community by sharing your journey. 

Beyond the results/ leaderboard this is about community engagement. We want you to share the journey to your own finish line via any and all social media channels. You can tag us on facebook, twitter or instagram under the hashtag #centurioncommunity. Photos are strongly encouraged! We will share what we can and award spot prizes to the best uploads and engagements over the course of the event.
