Yes, run. Not drive, or bike, or get towed. Running.
Recently a guy beat the world record for running the most miles in a single day. He collapsed 8 minutes before 24 hours, and had 1/3 mile left to beat the record. Got himself up and beat the record by 5/16th of a mile.
154 miles with just water in 24 hours. Unbelievable.
