Unfortunately I couldn't get to the Yarra Bend Enduro in the morning due to goal umpiring duties (Fitzroy U9s d Macleod by 101 points).
Instead I had a spare 80 minutes in the afternoon before Mason's swimming, so I tried to do most of the course. I ended up doing 14.5kms, going clockwise and dropping 39, 47, 21 and leaving a loop out at the end including 22, 34, 49, 24 and 30. I think this would have added about 4.5kms and around 25 minutes.
It was great fun to add the 2hr score event challenge to an area that I usually just run around on the trails. It forced me to choose some routes and trails that I don't take very often.
