Yes, if you stay in the sub 75 you can keep going, but I honestly dont race in that range...ever. Not even a marathon. That is about where I do my long runs and easy training runs. I dont typically heart rate train, but just like food, I spot check. The year I was running well 75% was right around a 10 minute mile and my marathon pace was 8:30. I certainly didnt stop to take my HR during the race, but clearly well above 75%. 5K pace at the time was something like 7:22. I'm guessing near the end of that race I was nearing that 100% I've gotten tunnel vision at the end of a 5K
