Anyone interested in doing the Paris Century or the metric should register by Sept 9th to avoid the price increase. One day or two day options available. You can register online or print a mail in form from the website to save the imathlete fee. Where else can you ride and have a rest stop at the second tallest Eiffel tower in the world?

Forgot to add the dates, Oct. 5-6. The link is titled from last year but will take you to the right place.
