This is an annual event and involves walking between Glasgow and Edinburgh in support of BHF.
It's 100km, with an option to walk approximately half of the distance to the Falkirk Wheel.
To set the scene, it might be sensible to pencil in 24 hours to Edinburgh, and about half that to Falkirk. Faster and slower is also possible!
I'm posting it here because I might organize a few "training" jaunts prior so that people can build themselves up (if needed!). That might enable people to pair up with walkers of similar ability.
