I did the Raid Pyreneen Reverse in early June 2013, as part of my training for LEL.
We had a small 8 person group - apparently folk were put off by the 4 day plan, instead of 5.
The organisation and support were absolutely first class: unltd bananas & cake en route, allsorts breakfast cereals [albeit not porridge in Fr
], pasta at hotel, good company, excellent gpx routes, support wagon [handy for those with Di2
]
I could not recommend Marmot too highly.
Have a good ride.
