While I was on the back portion of the out-n-back of Sunday's run, I thought about the two primary differences in my running style. Though consistent throughout is a stumbling, lurching, ham-footed physical component, the philosophy of how I ran was quite different between the two.
Thursday was a SLOE run. That's an acronym I just made up for Same Level Of Effort. When I say I had a SLOE run on Thursday, I mean it was the type of run where I don't ease up on downhills. (Flats? Ha. Not to be found anywhere I run.) Whatever effort I am putting into the climbs I try to maintain on the downs. While going downhill, I try to keep my breathing extended, and heart rate up. Typically, I try this for runs less than 10 miles. It fits with the "do every run like a race, and every race becomes just another run" psychosis I've read about. It worked on Thursday, as I "blazed" the afternoon run.
I partook (partaked?) of the other run type on Sunday: The SUDS run. I also claim creation-credit for this as a running philosophy acronym. A SUDS run is a Same Up Down Speed run. I typically do SUDS runs on longer, or more relaxed runs. How I do it is thus: Since nearly all my runs start uphill, I set an uphill pace that I can maintain for mile after mile. For me, that's an 11--14 minute mile depending on the expected slope. I "set my gear" and go. When I hit a downhill (or on the downhill part of an out-n-back), I don't increase the speed, I use it as a "breath catcher" and to ease the strain on the legs. This methodology has served me well: my longest climb doing this was 12 miles (Sierra Canyon to The Bench on the TRT), and it worked yesterday on the steeper 7 mile 4500' climb up the Ophir Creek trail.
Oh, and a SUDS run is one where I have beer at the end. So a SLOE run can still have a SUDS finish. Some imagery from Sunday:
