Thanks @OhOneOhTwoOhThree .
It started and ended on sand, and it was mixed terrrain, so deciding on which pair of shoes to make me faster was futile as it was never going to be that sort of race. I wore trails last year, but this year I got away with road shoes, even if my feet got wet at the end.
It is hard to get any forward motion going on the sand, but I leaned forward and took light steps not quite letting my heel touch the ground before taking the next step. It felt easier doing it this time round. I don't know whether it was technique, shoes or just the laissez faire approach I had which took the pressure off somewhat.
Welcome @JantoDec and @whatsit84 . I hope your first half goes well at the end of next month.
I used Runna for a week during the free trial, and to be honest, the times they predict you are way too ambitious, and the workouts are far too intense for me when I did it. I know some people love it, but it wasn't for me.If you own a Garmin, they have their own programs for free you could try.
