EP...for most first timers i think it would be hard tp drive home as they do not know how their bodies will react.......
that said a lot will find it hard to drive the next morning as they will have stiffened up by then.......
i would advise all first timers to have someone else with tyhem to drive home if necessary or to wait until the tuesday.....
some people need drips..others have bad stomach issues after the adrenaline of the day starts to wear off.some have pulled muscles etc and some are just totally fatigued especially if you had poor sleep prior to the race,,,,,,,,
others can get up and do an ironman the next day
