I agree. That is why I stated “endurance ride” rather than race.
Perhaps where you live the rules are different. In, 06 I did a 25 mile AERC sanctioned LD in 3:18 min. and that was coming in 8th. No disqualifications.
So, that is why I asked whether you were riding in a competitive trail event rather than an endurance event. I understand that CTR’s dictate your pace vs. endurance rides in which you have a maximum ride time but no minimum that I’m aware of.
Edited to Add: Thanks Bonnie. I thought he was speaking of a CTR. I’m not up on CTR rules so wasn’t sure. And yes, there are 25’s and there are 25’s. Some will take longer than 4 hrs and some less.
