My First Half Marathon	post	/assets/blog/running/time_vs_distance.svg	/assets/blog/running/time_vs_distance.png	A scatter graph of run time vs run distance for all my runs on strava. It shows that I mainly run between 5 and 6 min per kilometer, regardless of distance

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
