Four Rounds in a day

I've put myself forward to play 4 rounds in a day at four different courses, anybody ever done this, and how tough did you find it?

Hope the 4 courses are near by   ::eek::

I hope its for a good cause!? Still at least if your playing four rounds, theres a decent chance that at least one of them will be good!!!

At the age of sixty I was still carrying my bag and did three rounds in one day at Camberley Heath golf club wiith three other friends. I might add that we ate breakfast lunch and dinner, before, between and after the rounds. The green fee was £32 per day then.
