HBT handicap race

My son runs for HBT - the Hunters Bog Trotters - dont ask. Today was a race round Holyrood Park. I went to watch. Was not expecting it to be an obstacle race. R reported he had to drink 2 pints of beer on the way round and he does not usually drink alcohol. The finishing line was a dive through a hoop - extra. Not the best pics but it will certainly remind me of my day. I had climbed up to a ruined chapel for photos but there were far too many tourists
