Mon: AM - 10 miles with light fartlek of 8x45s fast, 2:15 easy. Averaged 4:48 for the fast portion and 7:27 for the easy sections. This is a similar workout that I've done in the past (8x.15 fast, .35 mile easy), except that it's about 30 seconds less in recovery. Leg turnover felt good and fast. PM - 5 miles easy (7:18)
Tue: AM - 7 miles easy (7:23); PM - 4.1 miles easy (7:26)
Wed: AM - 12.8 miles including 4 miles tempo, 1 mile jog, 4x90s downhill. Plan was to run the 4 miles tempo starting at 5:30 and then work down to 5:20. I never felt liked I warmed up with the temps at 17 degrees (9deg real-feel with 12mph winds). I came through 1600m in 5:31 feeling like it was harder than it should have felt. I tried to pick up the pace on the 2nd mile, but it just wasn't happening with the freezing temp. After running the 2nd mile in 5:33, I thought about calling it quits. Decided to just finish the tempo running at least the same pace. Ran 5:33 and 5:28 for the last couple miles (3200m to be exact). Afterwards, I jogged a mile to the hills where I did 4x90s hills at mile effort. Covered .32 miles of downhill at 4:43 pace and took some pounding on the legs. PM - 5.2 miles easy (7:02)
Thu: 12 miles easy (6:56)
Fri: AM - 5 miles easy (7:23); PM - 6 miles with 6x20s fast pick-ups (6:55)
Sat: 20 miles long run with middle 12 miles moderate progression. First 4 miles easy, then 12 miles moderate progression from 6:30 to 6:00, and then the last 4 miles cooldown. Averaged 6:14 pace for the moderate progression and 6:27 overall average for the 20 miles. Pace felt smooth and comfortable, but the legs started to feel a bit tired in the end from all the rollers.
Sun: AM - 6 miles easy (7:12); PM - DNR; family time trumped putting in a second run.
Weekly Total: 93.2 miles on 11 runs/7 days
I can tell that there is cumulative fatigue starting to creep in, especially with the mileage increase of about 10 miles/week each of the last 4 weeks. This (cumulative fatigue) is actually a good sign and necessary during marathon training.
