I just ran my first half marathon. To celebrate the occasion I'm going to have a look at my historical run data.

|
|
|
- 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 parametrized 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
