Two More "Coached" Workouts: Long Run Fartleks and Long Intervals
>> Tuesday, August 18, 2026
I sort of kicked off TC 10 Mile training with an old "Coach Jen" workout of running some hills at the end of July, but that really set off my calf pain. Oops. The following week, I did a "normal" long run on Monday and a "Coach Jen" tempo run on Friday. That tempo run went WELL.
The week after that (last week), I added in 2 "Coach Jen" runs as well: I did her long run fartlek workout on Monday, and her 2x2 mile interval workout on Friday.
The long run was a longer warm-up, 4 x 0:30 sprints to get the legs "feeling snappy," and then 2x (1 min, 2 min, 4 min, 5 min) with 50% of the effort as easy running after. I didn't really have any goals, other than to try to keep the first half-mile of my 4 and 5 minute efforts to 3:00 or faster (which I did nicely in my first set of fartleks). Here are the splits of my fartleks:
1: 0.18, 5:41 pace
Easy 0:30: 0.07, 7:38 pace
2: 0.36, 5:36 pace
Easy 1: 0.13, 7:33 pace
4: 0.69 (2:57, 1:04), 5:51 pace
Easy 2: 0.26, 7:45 pace
5: 0.88 (2:51, 2:10), 5:41 pace
Easy 2.5: 0.31, 8:02 pace
= 2.88 miles
1: 0.18, 5:34 pace
Easy 0:30: 0.07, 7:58 pace
2: 0.35, 5:41 pace
Easy 1: 0.13, 7:56 pace
4: 0.68 (3:00, 1:01), 5:57 pace
Easy 2: 0.25, 8:11 pace
5: 0.85 (3:00, 2:01), 5:54 pace
Easy 2.5: 0.31, 8:11 pace
= 2.82 miles
(shorter in 2 efforts and 1 recovery by 0.01, and shorter in the final effort by 0.03)
Note that my first 4 and 5 minute efforts were fast (5:51 and 5:41 pace!), but the same 4 and 5 minute efforts at the end of the workout were slower (5:57 and 5:54 pace, with the opening half mile of both of those being 3:00 [6:00 pace]). I was hashed. I did this workout 2 years ago at the same point in my TC 10 Mile training, and I was a bit faster then: I covered 2.89 and 2.86 miles then, and only 2.88 and 2.82 miles now... so a bit less now, but not DRASTICALLY less.
LOTS of splits in this weird, fast, long workout.
(Split #6 was the start of my 4x30 sec efforts,
and split #33 was the end of my final 5 min effort.)
Pace and heart rate.

Then on Friday, I did what has since become an "old classic" workout of mine: 2x2 mile intervals with 3:00 rest between. These are done on a running path... not the track. I started the first one with a 2:53 opening half-mile split, and I was thrilled about that because I was ready to TRY to be fast and to SUFFER. And I was proud of these splits:
#1: 2:53, 2:58, 2:49, 2:52 = 11:32.9
3:00 walking rest
#2: 2:49, 2:53, 2:53, 2:52 = 11:29.4
That's among the faster times I've done this workout! I know I've done this (YEARS) before in sub-11:30 for both splits, but to be just over that for the first one and just under it for the 2nd is great! (My PR for this workout is 11:28 and 11:24.) And it's FASTER than I did this workout in 2024 where my first one was way slower (11:42) but then my final one was a bit faster (11:27). And I was even slower back in 2010 when I was first given this workout by Coach Jen.

Standard. But I don't believe that spike in HR half-way through the final interval.
My Garmin does that sometimes... it's not my heart. I don't think.
Back-and-forth a bunch of times on the grass.
4 of each: high knees, butt kicks, grapevines, and sprints.
