Thanks again Jet,
This sounds doable but I will need to get a base of my HR first. Also a monitor with HR and Cadence would be good too.
I have been able to ride 22mph for a mile or so and even higher. It seems my average tails off at the end of the rides. I look from time to time and have had 19 avg at 25 miles but that might be 4/5 of the way or 1/2 of the way and by the time I get home it is 17.5. Also all my posted times are from garage to garage with all stop signs and red lights in there as well. so maybe I am not that bad after all.
