Use the bus with the enduros, times were limited last year, but I have taken the ‘bike’ bus back (as pedestrian) sometimes and there were never any bikes in, or other than that you can manage Chx to Arg by the river, warm ya legs up before the main ride begins.
The Brevent-Samoens route can get very busy cos it’s the GR route, and there’s the ladder section, a climbing sling is sometimes of help.
You’d be surprised how busy the trails get with walkers, the valley trails can be horrendous and although being very polite, it is annoying with verbal abuse, but it has to be taken with a pinch of salt and is forgotten after.
Lovely early morning rides and evening rides, but you’ll have to pedal more.
One of my favs is the Possette but again out of bounds July/Aug
I think Tom’s book is ok, but personnally I was a little bit disappointed, perhaps cos I already knew most of the trails as walker/biker.
