Another 1.5 miles on the treadmill convinced me... those Asics Nimbus 10's are not for me. They go back tomorrow. I'm really disappointed in that. I might try the 11's... but from the local Athlete's Foot here. I dropped DS1 off at soccer and then jogged to the nearby H.S. track, almost a mile away. Then I did several (6? lost count) 200 m intervals with 200 m recoveries. Sometimes I jogged, sometimes I walked... Turned off my timer on the Garmin a couple times when I meant to hit the Lap button. (I was doing this manual, not with the interval function) I'm really not very good at keeping track of this stuff, but I did seem to manage several 45-49 second intervals, which was cool. Not sure that I can string 8 of those together for my mile race on Thursday, but it was a good test... Oh, I wore my Nike Air Pegasus shoes... they seem ok. Holly and Enke, I order a bunch of shoes at a time and try them all out. Usually send most (if not all) of them back. That's why Zappos' free return shipping is so good for me... I have really hard to fit feet, so go through more shoes than Blondie Bumstead trying to find a pair that fits!
