Set off at a solid but relatively comfortable pace and just tried to hold it and keep consistent. Had to work a bit between 7km and 8km in the full sun but generally pretty good. All km splits were between 3:42 and 3:47 apart from the final one pushing on a bit to finish in 37:02.
Been a great holiday. Haven't been as relaxed or slept as much in a long time. Some pics of our house here:
