La Resistance contains some sections of highly technical gravel/unmade roads, with embedded rocks and loose surfaces. These sections require a lot of concentration when riding with a road/gravel bike, with the need to pick your line to avoid pinch flats etc. (they are also brilliant fun!).
In the spirit of La Resistance, this is a self-supported ride, and every rider must carry a spare tyre, at least two inner tubes and pump/CO2, so you can keep moving in case of minor problems such as punctures.
Each ravito will also have a pump, spare tubes and allen keys for you to use
