Hi, I notice looking at AUK's calendar events that some brevets are Brevet Randonneur and some are brevet randonneur des Mondiaux.
Googling about and looking at the FAQs here I can see that they are organised by different bodies but are there any other discernable differences between BR and BRM events? It looks to my untrained eye that BRM events tend to be more arduous but I cannot see anything else obvious. I may think about entering a BRM event and wouldn't want to inadvertently screw up and break some rule that I'm unaware of.
Cheers.
Rough difference is that with BRM there is no extra time allowance for the over-distance. So you get 13hrs and 40 mins (from memory?) to ride a 200 - whether that 200 is 205km or 220km on the road - makes no difference. Whereas BR - you will get an extra however many minutes/hours to cover the over-distance.
So BRM is a little more stringent - but nothing to be worried about unless you are at the slower end of the scale.
BRM events are important for qualifying for many continental events (such as PBP, where your SR needs to be BRM).
In non-PBP years, fewer rides will be BRM (because it costs a little extra to have it validated by ACP).
It's one of those weird anomalies that probably at some point needs to disappear.
Really - don't worry about it unless you are really at the back end of the field. Once you finish, your results on the AUK website will have the ACP brevet number next to it. That's all.
