Yes, no, maybe?
The full 2500 km monty looks pretty challenging and the entry fee quite steep, seeing you get a bit of tat and a GPS tracker for the money. No food is mentioned.
That said, the 1100 km self supported is more affordable, should take in the best bits (alps) and should be more civilised... 5 days to cover 1100 km seems alright to me... still not sure why I have to pay 180 Euro for a GPS tracker and a goody bag, but maybe it's all worth it?
Anyone thinking about it?
