Little Circles has an awesome post where he summarizes the equipment and food he used on a recent 226 mile New England ride. In his post-ride breakdown, he covers saddle balm, energy gels, front and rear bags, rain jacket, lights, and more. I’m in the process of adding to my collection of gear for long distance riding, and I’m sure I’ll refer back to his list again when creating my own wish list of bike gear. If you’re into riding long distances, definitely check out his very helpful and thorough post.
This article from OregonLive offers a good introduction to the sport of randonneuring. It also includes a glossary of key terms. I appreciate that the article is written by someone who had just finished her first 200k brevet, which gives it a good beginner’s perspective.
