Notes
Fixed the file. PB, very happy. Had a stiff hamstring all week, so worried about that but after 2km into the race it felt fine. Got to 5km feeling comfortable, but by 10km was starting to be concerned about holding the pace. I then switched to running / km and just focusing on holding 3:46/3:47. By 16km I was confident about holding the pace for the last 5km, then the hill arrived. Worked really hard up the hill, then ran down the hills as hard as possible. By 20km it was about maintaining, then hit stop on the watch instead of split. Only realised 40 seconds later and resumed.
Very happy with the result.
Halfway: 39:56 / 39:50
