Just to chime back in, this thread was more popular than I thought it would be,
I was wrong when I said 6:40, I ran my half at 6:30 pace, it was 1:25:50 when I finished.
I signed up for that half on Wednesday, took one day off on Saturday, and ran on Sunday (Won it btw, but I live in a rural area). I did this with no real taper and no training for that race. I was running 45 mpw, Fridays were 5x1k inside of 6 miles, Sunday was 4T inside of 8 miles, and Wednesday was 13 slow.
Since then I've been following Jack Daniels 2Q plan, capping at 70 mpw, to a TEE! My intensity and mileage is WAY UP!
Sorry, I feel like I need to defend myself a bit. I'm not some idiot who picked 3:00. I ran a marathon 2 years ago shooting for 3 hours and BLEW UP! I was on pace until mile 18, then at mile 21 had to jog/walk to the end. Finished in 3:15.
I didn't follow a plan, I ran every single run at moderate effort. I did like 8 20 mile runs. No speed work, no tempo work, nothing, just ran pretty hard every day. After that race I picked up 80/20 running and some other books and trained off that ever since.
Again, my training has been going great, this post was mostly me complaining about 4x2t, 2x1t being insane, especially 3 days after 12M in a 17, which it seems like everyone agrees it is. I am going to shoot for 4x2T and leave it at that.
