Kind of interesting to see how distance impacts pace

Nice graph.

I tried to do mine but swivel removed the first set of points and gave me a bar graph.

I'll try it again later.

It would be more useful if you plotted the data on a semi-log scale (base 2). (i.e. 500m,1000m,2000m,4000m, 8000m etc would all be equally spaced.)

Then dots would be much closer to a straight line and more useful as a prediction of other distances. It would also be easier to see what distances are relatively slow or fast compared to others.
If your times followed "Paul's Law" all the points would be on a straight line with a slope of 5.

Somehow it lost the 1st set of data, and reproduced the graph 14 times.

I have tried to delete them one by one but they keep showing up.

It's a nice system - hope I can get it to work.

I agree, but Swivel doesn't seem to offer log scales.
What about Google's document management system? Maybe that might offer log plots.

manually calculated logs

the graph shows that my 2000 pace is slower than the other points would predict (about a 1:48 pace), which makes sense because I've been avoiding it since the first try

Agreed, you may be do for a PR at 2000m!:D

Thinking again, it would be clearer to plot log2(km) on the x-axis. that way,
1000m would be 0,
2000m would be 1,
5K would be 2.3,
8K would be 4
10k would be 4.6 etc.

I think it would be easier to figure out then to realize that 2000m is a bit under 2^11
