On Friday I had a nice, leisurely 58.54 km ride but my Garmin Edge 705 went haywire:-

Distance:986.39 km

Time:02:49:52

Moving Time:02:48:11

Avg Speed:348.4 km/h

Avg Moving Speed:351.9 km/h

Max Speed:29.1 km/h

On one of my routes there is a TV station that sometimes sends the heart rate or speed haywire. Should I contact the Guiness Book of Records?

Interesting hypothesis. I sometime get that on my computer too. I thought my wires were going bad and was getting ready to take everything apart to look for problems. I do ride by radio towers, though.

Thats why we love our Edge 705. I sometimes ride 75mtr. below water level :jap:

all garmin products have issues w/elevation. i sometimes ride up & down 5k meters worth of elevation ;-)
