I am a cyclist and I used Excel to track my rides.
Column 1-Date
Column 2-miles (which I have no problem with
Column 3-time on the bike
I am looking to to see how I can add up all the time I have spent on the bike
I.E
Ride one 3:20:58
Ride two 2:27:33
So on and so fourth

I have clocked well ver a 100 hours. But when I hit sum I get like 7.19

Does this make any sense???
