We have had lots of physical challenges. How about a mental challenge such as visualization? A good deal of running or any sport is mental. And from what I have found, there is not much training going on in this area, nor is there much written about mental training.
So how about everyone spend a couple of minutes a day visualizing a goal, preferably a running goal, but a non-running goal would work as well. It could be a work goal (promotion, dealing with a difficult person), a personal goal, or a health goal.
Visualization in any form is good exercise to help meet goals.
