The first round went surprisingly well and the second was pretty good, getting them into the clubhouse for lunch just as the regular field teed off about 11.30 am.
Once the field was gone it was round three with lots of encouragement from family and friends and despite Chris's sneaker blowing out the two made progress although one concession was to stop scoring which made the golf more relaxing.
They finished their fourth round before sunset at about 6.30pm admitting the muscles were starting to tighten and the looking for balls more cursory.
They still had a few balls left and the energy to make it to the local tavern for a celebratory and well-earned ale or two. both feeling very proud of their achievement.
Sunday was spent sleeping and recovering but both made it to work on Monday in "pretty good shape".

Already they have raised more than $3500 and the total for the nation promised so far has passed $3 million – all going to the Cancer Society.
The society says completing the four rounds is the equivalent of running a marathon.
