Have you heard of virtual running/fitness challenges? The basic structure is you sign up for a challenge, set a completion goal, and track the distance you do (or convert other activities to distance, and on completion you get a medal.
I did a couple of Warhorse 100 mile challenges (Journey and Ranger) in 2020, one for each horse. Warhorse donates part of each entry to a different charitable organization for each challenge.
Then I kept seeing ads for Hadrian’s Wall on FB early in 2021. It was 90 miles and I thought it would be motivation to go and ride through the cold, tail end of winter and into the unpleasant mud/ice/rain/snow cycle of early spring. I signed up.
And discovered the Conqueror virtual fitness challenges (Hadrian’s Wall was one of theirs). They have an app where you can add your distances, check out Google street views of the route you are doing (I found a lot of Roman ruins along the wall), and for every 20% completed they plant a tree in partnership with an organization that plants trees in places around the world (I think Haiti post hurricane was one) or pays for plastic to be removed from the environment (another partner organization). There are “postcards” with information about the area and history sent at specific points along the route. There are challenges for routes all over the world and at many different distances.
After I completed Hadrian’s Wall I went on to do two more. I signed up for Warhorse challenges again in the fall (older horse knocked his out in 33 days, while younger horse had some health challenges and is still working on his). Even it’s only a mile or two at a time the distance adds up. My winter challenge is another Conqueror – 500 miles around Scotland’s North Coast - intended to keep me going all winter. I am behind (as far as % distance vs % time completed) but I expected that as my winter distances will be shorter and we’ll make it up in the spring as rides get longer.
You can structure your virtual challenge however you like. Some people count every step, others only intentional exercise, others only a specific type of exercise (walk this one, cycle that one, row yet another, etc). I only count riding, or hand walking trails for mine because the point is to get me out doing something with the horses. There have definitely been days where the idea of adding to my challenge distance have gotten my bum in the saddle when I might not otherwise have ridden!
