Did a 5k run using my wahoo today, and my time was quite different from my running buddy who had a Garmin running watch (not sure which one but high end).
I’ve checked my wahoo is 200 meters short on distance over 5k, so 4% out. (Not due to gps thinking I was cutting corners or anything, and it’s short so not an over estimate due to gps zig zaging around actual route).
Comparing the data, I noticed that his data appears more detailed - seems to be taking more readings. Is this a running watch v bike computer thing? wahoo v garmin?
