My wife surprised me and ordered me a Zero Runner for Father’s Day. I was excited and very surprised. She went and picked it up in Aurora at 2nd Wind Exercise. I put it together yesterday and used it today. I wasn’t sure ahead of time how far I was gonna go; my body felt great no pain in my knee (and still have no pain) so I kept going. 13.1 was what I did for my inaugural Zero Runner workout. 13.1 in 1:41 – I was tickled. I know after one session with the Zero Runner it’s going to make me a better runner.
