For each of the past few years some friends and I have undertaken the Macmillan Cancer Support Longest Day Challenge which involves raising cash for them by playing 4 rounds of golf in one day. This year we clocked up just over £2500 and we had superb support from our home club (Drift G.C.) and the club's captain.
So if you want a good excuse to cram in 4 rounds in a day next summer, you now have it and you can feel good about raising some cash for a very worthy organisation.
