I ended up downloading and using an app called Ultrachron Lite. It was free, but more importantly, it lets you use the hardware buttons (volume up & down) on your phone to mark the laps. No fussing with the touch screen while “sprinting.” It also lets you email yourself the timing stats when you’re done.

I also ended up using my neighborhood streets instead of driving to a track. 2 long blocks = 400m speed intervals, 2 short blocks = rest walking intervals (200m-ish).

Speed interval lap times:

1. 00:01’56”67
2. 00:02’01”79
3. 00:02’03”71
4. 00:01’55”90

I was supposed to be running 2:15s to be on target for a 9:00min/mile. I tried to make myself slow down, but that’s the speed my body wanted/needed to run last night. So I let it go.

I was surprised by how much I really enjoyed the structured intervals. And I’m wondering why it took me so long to finally try them.
