This morning I went for a ride on my road bike for the first time this year. The dirt roads I mountain bike on were too muddy. It was 27 deg. and calm when I left home but I started to get a slight tailwind just before the turnaround. which then became a headwind that got steadily stronger and slowed me way down. I don't mind headwinds to much as long as I get the benefit of the tailwind going the other way unlike this morning..
I mounted my Garmin to the handlebars and compared it to my bike computer. The current MPH was amazingly close. Usually the same. sometimes within 0.1 MPH and never more than 0.2. The average MPH at the end was identical at 16.5. The currant pace given by the Garmin while running dosen't seem very accurate. The extra speed on the bike must make the difference. As far as total distance, the Garmin read .09 shorter than the bike computer. I guess thats not to bad after 23 miles.
Total time 1:23 ave. HR 144
PM Ran 2 mi. with my son then 2 more myself. |
