I am a college runner who is finally doing high mielage this summer. I have always peaked at 75 and averaged around 60. This summer I am doing 90 mile weeks and I was wondering what kind of improvement I should look for to set my goals for the up coming cross-country season. I have run 25:55 for 8k. is it reasonable to think I can run 24:55 or am I way off base. I am also doing 8-10 mile threshold runs. Thanks.
