[El Gordo]

For simulated marathon running, just climb into a tumble-drier (TIP: the larger, industrial ones are the best - you may have to develop a relationship with your local dry-cleaning outlet), along with a variety of sharp, heavy objects. Ask someone to set it going, and trust them to come back 5 hours later to turn it off and let you out.

It saves a lot of wear on your trainers.
