My final result was 189 km. I felt absolutely exhausted after 3 hours and knew then it was going to be a brutal fight all the way to the end. Then I got hit by cramps and the only way to treat them was to have a massage every 4 laps. I must have spent about 2 hours with the physio, in which case 189 k was the absolute max.
I need to do some soul searching now. I think I need a complete rest from running for a while.
