Yes but, the culture here is one of the Rondenneur. They ride like 1200 km in less than 80, 84, or 90 hours and most don't ride like it's a race. They likely prefer not to vibrate down the road as fatigue is a big issue and there's a premium on comfort. They use lights, bags and many use fenders as well: like my road bike.
A friend of mine has done Paris-Brest 3 times. He often trained by riding his bike to work (about 30 miles), then after work on a Friday he would ride until 8-hours before he needed to go to work on Monday. Probably a factor in the divorce.
It was interesting to hear how he and his co-riders often hallucinate.
