For those of you doing the Paris Roubaix Challenge I have set up this meetup as you are probably going to want to organise yourselves and the original meetup is going to get buried soon.
Post what distance you are planning to do as well as how long you are planning on staying in roubaix and you should be able to sort out a logistics plan.
There is still time to sign up if you want to do it:
If you are planning on doing the full distance remember to think about how you are going to get to the start (there is a shuttle bus which we used last year €30 and early start but worth it)
there is an f1 hotel which is really cheap here : https://maps.google.fr/maps?q=50.706579,3.160098&ll=50.706569,3.159959&spn=0.002144,0.004994&num=1&t=m&z=18
and a pretty good restaurant here: https://maps.google.fr/maps?q=50.710092,3.159382&ll=50.710075,3.159433&spn=0.002144,0.004994&num=1&t=m&z=18
and in the centre of Roubaix here : https://maps.google.fr/maps?q=50.710092,3.159382&ll=50.692269,3.174915&spn=0.001079,0.002497&num=1&t=m&z=19&iwloc=lyrftr:m,6644370361270896721,50.69228,3.1747
I suggest you copy these addresses as Roubaix was a complete ghost town last year on friday evening and it is really tough to find good places to eat.
If any of you are thinking of hiring a car and want to share the cost, put details of your plan here and i'm sure you'll find someone to share with.
You can find some info about what the pros ride here ... http://road.cc/content/news/80505-paris-roubaix-2013-tyres-wheels-chainrings-chainguides-and-directions ... Last year I rode 25mm gator hardshell tyres at 110psi and I got through without any punctures.. I wish I had taken more food with me instead of 4 spare tubes! I doubled up on bar tape to soften the vibrations a bit but my wrists still ached for about a week afterwards. I found that changing your position on the bars frequently helps ease the pain over the cobbles. Other than that I rode my normal setup.
One thing to check is that your bottle cages are in a good condition and are nice and secure (last year one of mine snapped half way through and i lost a bottle).. the first sector of cobbles we hit last year had about 100 almost-full bottles littering it.. this sector is going to expose most bottle cage issues and it is also where you are likely to be in a big group so stopping to pick up dropped stuff isn't really an option.
Have fun :)
