Last year I participated to the trial race Santorini Experience. It started at Oia and depending on the number of kilometres that you wanted to run, it may have 5, 10 or 15 kilometres. I ran 15 km of the magical path that connects Oia to Fira, overlooking the Caldera. During the race, I used the open source tracker for android RunnerUp, which is a simple but very complete tracker without all the bloatware that have some other popular trackers. This post shows some graphics of the data that I captured during the race.
RunnerUp records the coordinates,
time and altitude which I exported using a
.tcx format. The
tcx format is
xml format from Garmin, I converted to a
csv file using a script from
Then, I used pandas to pre-process the
csv file. The details can be found in the
The coordinates latitude and longitude can be used to plot the trajectory of
the race using folium library with a back end of Leaflet.
The race trajectory was symmetrical: 7.5 kilometres forwards to Fira and 7.5 kilometres backwards to Oia. It has 189 meters from the lowest point to the highest one. During the 15 km I have climbed 1486 meters.
I used ChartJS to plot my speed performance. My maximal speed was around 15 kilometres per hour and there are some parts of the race where I almost walked because the relief was too steep.
The first three kilometres were easy to overcome with a mean speed over 8 kilometres per hour. After the 4 kilometre it was difficult to keep a good average, then I have a average speed of 6.6 kilometres per hour. The speed oscillated with the relief and at the end I end the race within 1 hour and 40 minutes, having a average speed of 9 kilometres per hour.
A marathon needs to be prepared for at least 3 months. This post shows my preparation training and a prediction of my time for the Metz Marathon 2017
