Finishing

I was lying down for a good 40 minutes waiting to get a low angled shot of son R finishing his race.  He had run 22.5km in the hilly terrain covered in boulders and been out for 165 mins. In contrast my course, for the older lady, was about 4.5km which I managed in 48 mins leaving lots to time to hang around waiting for this shot.
Incidentally I was 24th out of 44 ladies in my class. I walked and did not get lost. The last lady, also a Brit was out for 85 mins. I wonder where she went?
