+- download all my runs from strava
+- scatter them on a (distance, time) plot
+- plot the (distance, time) curves predicted by the V02 max tables in the running book
+- interpolate the table to get a smooth function parametrised by V02max
+- fit that to my data
+
+- potentially will need to take only the top 20% of runs or something
+- and/or weight by time to get a better estimate of current V02max
+
+Extensions:
+- download heart rate data and make a histogram per hour of the day
+- could map radius to heart rate and angle to hour of day to make a nice figure
