3/4s are best. Though mentally hard to stick with. All that rest means running very hard. Hard to do for long. 3/3s and 3/2s are next best. Then 2/4s, 2/3s, 2/2s, and 2/1s.

I had been trying to just do steady state easy runs. I'm so slow this way. And don't enjoy it. I like being faster. I like alternating back and forth. I'm sorry but going back to intervals. I'd be very happy to get back to my slow times of previous years. 8.41 for 12, 7.53 for 8, 7.25 for 5, 6.59 for 3. My mileage was actually quite low all those times. 20 to 40mpw.

I worry about injury. But I don't have to go so fast.
