Calculating average speed
I ride on my own and have been doing this for the last 12 years. I am thinking of trying a local club so that I can ride in a group and have been looking at average speeds for different group rides. I rode today for 2 hours and did an average of 14 mph. However, along the way I calculated that I was stationary at lights, level crossing etc for approximately 10 minutes. Do I take this in to consideration, in which case I would have an average speed of 16mph ? I realise that average speeds will vary depending on climbs, wind, etc. My ride today took in a few very short climbs between 4 and 10% , other than that it was on the flat.
