I'm naturally pretty good at the 400 and 800. Sub-51 and 1:55 in high school off of not great training. A few years ago during a comeback I busted out a 53-high and 2:07 after 8 weeks of training (and still 10 lbs overweight). With another comeback I ran a 2:02 for my first race of the season after 24 weeks of training.
These aren't amazing times I know, but I think they show me that I can have some success at these distances. Unfortunately my comebacks usually end after 6-12 months when I get overzealous with higher mileage and injure myself trying to run 16 flat for 5k. I know it's not the fault of higher mileage, it's my own for pushing too hard. But I put in so much time and effort only to run these mediocre 5k times.
Maybe I'm going about this all wrong by trying to run 70 mpw with doubles, a long run, tempos, etc. I get caught up in the letsrun.com higher mileage mentality.
Maybe I need to to train more like a 400/800 guy where a 60 minute steady effort is my longest run of the week, and instead of double runs I'm strength training or doing bounding drills. I think I'd be happier, and maybe the reduced volume would be good for me (since I can't seem to balance volume and intensity).
Has anyone ever switched up their training like this? Anyone ever have a revelation where they realized they're not training optimally to their strengths? What were the results?
