Superb weather and quite varied circuit between singles, rolling passages, elevation. Markings correct overall also and ravitos provided. She is well worth the trip.

Catch-up hike for those, like me, who couldn't do Morigny-champigny. 😉
We would like to be able to split and be able to support all the clubs, especially lately with the Covid, which have been tough... 😌 Unfortunately we have to make choices, our club was separated into two groups, 1 in Morigny and 1 in Cernay…

Great hike, great weather, done with Marc.
Really disappointing that they didn't have more participants. It's really underpaid, considering how well organized this hike was.
