[Closed] One day in Chamonix - Recommendations?

Hi,

A bunch of us are heading to Chamonix for the weekend. We're going rafting on Saturday and a few of us will be taking bikes for the Sunday. Any recommendations for good routes?
The Planpraz/Brévent gondola is open, as is Les Houches.

I've seen people on here recommend a guide book on sale in Zero-G. I was hoping to have time to buy that on the Saturday and use that for inspiration. If not, I was planning to ride the Petit-Balcon to Argentière.
If anyone has any better ideas I'd be interested to hear them, including any guides/guiding companies that may be worth contacting..

Cheerso!
