It's really hard to tell what you want advice on based on that. I think you'll need to be a little more specific than that to get much advice. Also, this might not be the best spot for this. As near as I can tell, you aren't touring; you are traveling with your bike. Might be better off over at the road section. As far as time of year, the second half of June will have little traffic, but the cols will be open. I believe it was June 16th that the west side of Tourmalet opened this year.
