Attached please find chart 11465 with the viewer's Tot. 8 nm distance.
Last year, as crew I rather enjoyed the sail back, and got some helm time.
I mountain bike 10 miles, 3-4 times a week and was not tired at all at 2006 OCR, but that was last year.
Now at 55 about 2 hours of MTB with an average heart rate of 150 will tire me out,
Yeah, when I was out of shape in my 20 & 30's sailing the Tornado would wear me out.
