The 03 is 4018 kms long and is the pinnacle of “type2 fun” self-supported multi-day navigation that are Brevets.
There is 40,000m of climbing. It’s a no-frills “you are on your own” self-supported type affair. There is one official ride – the Brevet, but remember you can do as much as you want. Yes really. The mix is approximately 40% seal, 50% gravel, 10% other (singletrack, dirt,grass, etc)
This will be an annual event.
