Run2 distance are always multiples of 5k. 5k is the entry level (at least until we start run2pointlittle1 for kids), though we expect the most popular Run2 routes to be 10k or longer, as the 5k distance is already relatively well catered for by Parkrun and other events.
In theory, there is no limit to how long a Run2 can be. Indeed, we hope that over time, Run2 members will want to use the community to help them to run half-marathons, marathons and maybe even further…
However, in order to try to make sure that Run2 is for ordinary runners only, no official Run2 event can be longer than a distance that each of the three co-founders have completed.
As of today, that means that official Run2’s are capped at 20k, but you can be sure that we will be working to ramp that up over the coming months and years and we hope that your demands for longer runs will give us all the required proverbial kick up the rear to suck it up for the good of the community and continue running further. Feel free to lobby, poke and abuse us if we are not keeping up with your demands!
