OK, I'll say it: Valentine's Day is an annoying marketing invention. So let's go running instead! Glam it up in your best Valentine's day running outfit--think hot pants and glitter!!
Run is organised by the LGBT community of Paris in parc des Buttes Chaumont. Distances are either an individual 10K or a 6K with a partner. You can either sign up as a couple or if you don't have a partner, sign up for Opération Cupidon and you'll be matched with the running partner of your dreams the day of! Who knows, might be the most romantic 6K of your life!
