If you've ever opened up Duolingo and searched for 'Tour de France', you have our sympathy. Picking up the dialect of bike racing is not unlike going back to school and is no overnight thing. Not only are there an abundance of words and phrases that you've probably never come across previously, at least in this context, many of them are also in French, especially at the Tour de France. If you're new to it, it can all be rather baffling.
We've put together this glossary of terms that you can save in your bookmarks to help you out while you're following the Tour de France, and next time a commentator tells you there's an echelon in the peloton you can nod sagely rather than going down the google route (again), or ploughing on in ignorance.
