Maybe it could just be an expansion of the tutorial, after you complete the fight school there would be an option to move onto a running tutorial, showing the simplest ways of running in toribash. After the player has completed the tutorial they can move onto the challenge, which would basically be run from this point to that point (obviously the first challenge would be quite a short distance), once the player has completed the first challenge then they move onto a more advanced running challenge ect ect, and then having the final challenge as the fastest run in the book of records. This would also work for other things such as learning basic tricking (like backflips and flash kicks), countering shovels and snap kicks ect ect.

Overall it would give people a couple new goals to achieve and make toribash a bit more friendly to new players. Also sorry to fleshmon if I took what you said the wrong way, this was my interpretation of what you meant by challenges.
