Running on the treadmill and reading

Ian was working with a different therapist for PT yesterday. I was speaking to mike on the phone when they started on the treadmill. When I arrived she had him going 1.7 mph! I was a bit surprised but thought maybe it was a strategy on her part. When he finally protested and I asked if we could turn it down a bit. She said his usual therapist had in her notes that he could go 3 mph with a 40 degree incline! She must have written it incorrectly or something but he did pretty amazing with it anyway. He was reading at that speed but more comfortable at the slower speed of 1.5.
