So, an update after a year on NSA. I was in good shape last fall, but there were no local races. Then in January I got injured – not from overdoing it, but from trying to run a workout on a crowded indoor track with sharp turns and a lot of pace changes. I tweaked a calf, and it cost me a month. Then after some progress, I fell during a workout and had a nasty fatigue reaction and lost more time. After 3 months of mostly lousy training, I started over in mid-March with some ridiculously slow workouts (like 2 x 1 mile at slower than MP).
The thing is, even doing 3 ridiculous workouts a week gave me more average workout volume per week than any of my race buildups in the last 5 years. Those big workouts I was doing looked cool, but they were taking so much recovery at my age that my weekly training load was actually pretty low. After a week of doing ridiculously easy workouts, I was able to start increasing pace and volume and got up to 4 miles/workout before I decided I felt okay to try a 5K. (This is why I think it’s okay for beginners to start NSA at relatively low volumes – I’ve done it myself a few times.) The race went fine off of 3 weeks of training, although I ran slower than last summer when I started NSA, and it left only 7 weeks until my goal half marathon.
I switched some things around. I stopped lifting because it was keeping me from recovering completely. My form felt like garbage, so I added a few pre-workout strides that focused on arms, knee drive, glutes, and driving my feet into the ground (and it actually helped a lot). I switched to doing the same 3 workouts each week: 3 x 3200, 4-6 x 1 mile, and 7-10 x 1K.
That meant a HM build with relatively low mileage (47/week over the last 8 weeks, peak of 55), with just a couple of 13-milers for long runs and a “peak” workout of 3 x 2 miles at 6:36/mile, which honestly is kind of a joke. It was also my shallowest taper. Seeing the graph of sirpoc’s CTL vs. 5K times finally clicked for me, so instead of a last workout 12 days out and then tapering, I did regular workouts the week before race week. I did cut back mileage and workouts for race week, since I’m old and a HM is a long race.
The result was that I ran my goal half marathon in 1:22, averaging 6:17/mile (in Vaporflies), right on pace from mile 1, with miles 1-12 not varying more than a few seconds in either direction, and just slightly faster on mile 13. That seems like a pretty solid result for 10 weeks of training coming off of an injury. It’s the same time I ran in this race 2 years ago, but when you’re past 50, running the same time as 2 years ago is a victory. If you believe in age grading, it was my third best race ever. I’ve been training seriously as an adult for 10 years, so I can say that NSA is at least as good as anything else I’ve tried (and I've tried a lot of different things), and I’m sticking with it.
Now I’m experimenting with one change in my training. Before the HM, I was focusing on building workout volume, but I was up to 30% or more of weekly volume from sub-T workouts, and most of my paces ended up in the 20K-MP range to keep the stress manageable. Now I want to get closer to the standard NSA paces by cutting back on workout volume and progressively increasing pace within the workout. Lots of volume at 20K-MP may have worked for a HM, but I think I was missing some of the benefits by forcing the volume and sacrificing pace. In other words, just do what works for sirpoc.
