Also very happy for you,
@SDSue ! That's great news! I'm still dithering about whether to do the 2-day in Ithaca. I'm seeing my doctor today.
I said I'd report on my submaximal: the sports centre staffer was very open and supportive, but had never worked with someone like me before. I did 18 minutes on a treadmill, going from a very slow walk to a medium jog before I got to my anaerobic threshold. He tested it by taking a blood test from a prick on my finger every three minutes, and stopping when I got just past the threshold.
The results were that my anaerobic threshold (he said we're always working somewhat aerobically and anaerobically, it's just that we shift from mostly one to the other) is 113 bpm. So, I'll increase the rate on my heart monitor from 97 to about 105.
It was disappointing that he couldn't give an evaluation of how "healthy" I was based on this, because apparently this can only be done by comparing one's submaximal effort with a test where you do your maximum, and I wasn't doing that. He also couldn't compare me with his other clients, as they are very well-trained athletes.
He thought at first from my self-description that I might not even register enough for the computer to give results, but I was "normal" enough for that.
I was crashed for 3 days, but not terribly. However, still very concerned about what maximal effort for 2 days would do (plus the trip, etc.)
Also, I contacted Jarod Stevens at Workwell a while back, and he responded very promptly. He said only Workwell in California and Betsy Keller in Ithaca are places he knows of that do the 2-day test according to their protocol.
