I'm in a weird position, one I've never been in before. So this summer I decided to go balls out with mileage and try to hold 100 mpw for as long as I could. Prior to that, I had spent a year - my freshman year - at more or less 80 mpw, and I saw limited success. I PR'd in the 3k (8:30) but dropped a couple of stinker miles when my PR from senior year of HS is 4:13. Overall I was fairly inconsistent. I realize now that it was because I wasn't resting properly before races, and I was loving training so much that I was content enough just jamming out mileage and not racing well. That's just to give where I'm at some context. So this summer I was running all 100 mile weeks, a couple at 85-90 in 6 days. Surprisingly, I never really became fatigued to the point that it felt impossible. It was a grind but it never felt like I was going backwards. If I ever felt truly overworked or anything I wouldn't hesitate to take the day off and then get back to training full force once I felt ready (hence the 5-6 day weeks). So right now I'm in great shape, and I'm working on properly tapering before races. So that aspect of my training is going well. My problem is that I still feel like I can bump up the mileage. Basically every day I'm running a 12 miler with a 5 or 6 miler either before or after. The runs are fine, if I feel good I run them fast, if I don't I don't. I'd say on the fast end, they can be done around 6:20-6:40, but the slow end isn't really any slower than 7:00. All of our runs are VERY hilly, so I'm getting great workouts in. Speaking of which, my workouts are also improving week-to-week. This week I had the best workout of my life! I'm racing an 8k in a week and I'm going to shoot for 25:15 or so, so that will be a good indicator of whether I should continue pushing a bit, or at least sustaining where I'm at, but what do you all think? What would you do in my position? I love to train, I'm not afraid of training very hard and doing this high mileage. I haven't been injured in like 14 or 15 months, and I realize that I have a limited time with the opportunities that I have (i'm a soph. in college), so I feel like I want to capitalize on it. Any insight from those who've been in a similar position?
