so nine pages later & with whatever the heck is currently going on, i'm going to turn the talk to training (sorry!)
what does this type of training run accomplish?
for a 1500/3K/5K type, will a steady 10-12 miler serve to maintain the aerobic benefits you gained from more specific work during the base period (such hard 15+ mile long runs for endurance, fast 3-6 mile tempos to bring down threshold, etc.)? and will it do so without leaving you so trashed that you can't do the fast work on the track 2-3 time a week needed to prepare for racing?
i ask because as a runner focusing on the 1500/5K this season, i'm finding it too taxing to fit a traditional long run (14-16) + longer tempo into my week and get recovered enough to do the fast stuff on the track. i'm playing around with the idea of scrapping the Sunday long/Thursday track tempo schedule i'm on & just doing one shorter, high-end aerobic effort on the trail on Sunday (say 10-12 miles of progressive running averaging out to around 6min per mile overall. the 2nd half of the run could start at 6min pace and cut down to the low 5min range by the last 1-2 miles).
i think Joe Rubio suggested something similar once, remarking that in-season he would scrap tempos and have his milers do 1-2 runs a week of around 10 miles in length where they would finish fast over the 2nd half (can't find the thread where he discusses this though...). these runs were by feel & would not tax them as much as a more structured tempos during base where they'd be trying to hit splits.
