I have been doing my long runs going up to 22 miles for Edinburgh marathon at 9 min mile pace as I would like to go sub four on Sunday. I have found that pace comfortable as I managed to chat with my running buddy. The question I have is is: should I stick to that 9 min mile pace on race day or should I push it a little and go for 8:45 min mile?!?! I have just read that in theory my long runs should have been done around 45 seconds slower than race day.
Any advice you can give would be greatly appreaciated.
