I am having some difficulty understanding the time limit for this brevet. The SIR website lists the dates and time from Saturday, June 20, 2026, 5:00 AM until Monday, June 22, 2026, which means you have until Monday at 11:59 PM approximately 67 hours. However, the RUSA website lists the time limit for a 1000km at 75 hours which means which means you have until Tuesday at 7:59 AM. Can someone please clarify the ride time limits.
