I'll join as well. Ran 2:57:42 at CIM last fall; targeting sub-2:55 for Indy this fall. I do short marathon cycles, so I'm not really training specifically for Indy until the end of this month. Until then, I'm racing short stuff (mostly miles) for fun and running form improvement.
As you'll see, I do a lot of cross-training. I'm a bit fragile, both because I'm over 40 and because I've got some auto-immune issues, so mixing running and cross training works for me.
This past week:
48 miles, 2:50 minutes of pool-running, and 2000 yards of swimming
M: Yoga and 80 minutes of pool-running
T: 12 miles, including a track workout of 6x800, 2x200 in 3:01, 2:58, 2:56, 2:55, 2:55, 2:53, 38, and 38 (recoveries of 2:20-2:3x between the 800s. Full recovery for 200s. (ran this one a bit fast for the weather). Light leg strengthwork and 1000 yards recovery swimming after.
W: 7 miles very easy (9:08), drills, strides, upper body weights/core, and 3 miles moderate (8:17)
Th: DIY yoga and 90 minutes of pool-running.
F: 8 miles, with one mile uptempo (6:16)
Sa: 4 miles very easy (8:34), plus drills and two hill strides, then DIY yoga.
Su: 4 mile warm-up; 5K race in 19:05 (6:11/6:07/6:47 for last 1.11), 3 mile cooldown. Much later did a 4 mile shakeout (8:40) and then 1000 yards recovery swimming.
Was happy with the 5K race (except for the fact I was 2nd). The course was very fast but the weather was tough - 75 degrees and near 100% humidity - so I was pretty happy with the time under the conditions.
