Adamski is going to check the track from Brest to Loudeac for AAA points. I logged (I think) 2400m ascent in these 175km and 4667m ascent in 415km from Brest to Villaines, which is a hilly but not savage 400. My feeling is that it added to my time, probably about an hour. As I tend towards hilly events, it wasn't a particular concern for me, but I did wonder about those who avoid hilly events being caught out, especially if it was hot.
I liked the new route through Alencon, which cut out that long boring undulating road to Fresnay-sur-Sarthe.
I'm not sure if it was new this time or last, but I preferred the old route along the D20 between Fougeres and TInteniac.
The new route from St Meen le Grand to Loudeac had a lot of heavy road surfaces, the old route, used on the way back was a bit nicer.
I did like the new route back from Brest, despite the hills, and wish I had done more of it in the daylight (my 600-400-200 schedule required a 4am start on this section). It would have been good to have food at the secret control or another food stop on this stage - they've done that on the hard stage on the way out with St Nicholas du Belem and on the next stage with Gouarec.
The route from Carhaix to Gouarec had a long section of main road which wasn't that pleasant, but the rest of it was really good and I liked riding through Pontivy.
