So I'm female, age 22 and about to run a half marathon on sunday. My first half marathon! I just want to make it through with a reasonable time but I'm not even sure what to consider "reasonable". Does anyone know the average time it takes a female about my age to run a half marathon? I ran 12.4 miles on fairly flat land in exactly 2 hours and I'm under the impression that this is fairly slow? Commentary? Is there some sort of table out there that has the average times per age group or something?
