I saw this ride about this time last year when I had just started riding. I was deturmined that I would go this year. Don't know if I am fit enough. Life kinda gets in the way of cycling. Working six days a week and an eleven month old daughter. But I'm seriously considering trying.

If anyone else is in Thailand, or planning a spur of the moment holiday, here are some details.

Just scroll down to Sunday 20 January.
