HillPace

HillPace is a library for planning running races. It can take the GPX of a route and a reference pace (the pace you would go on ideal conditions) and generate planned paces by segments, based on configurable external factors like the climb grade of each segment.

Status

This is a work in progress, but the core of the code is functional.

Installation

Go to the root directory of the package and run:

bundle install

Main dependencies

Important: Notice that geoelevation needs the whole SRTM database to work and it will download it automatically on ~/.elevations.rb on the first run (this can be hundreds of MB, but it is only necessary once).

Code organization

lib/hillpace: contains the core classes of the package, which manage paces, routes, segments and track points
lib/hillpace/input contains classes for importing routes (at the moment, just GPX)
lib/hillpace/pace_adjuster contains the pace adjuster and its strategies
specs contains the specs :)
example.rb contains an example of use (see the Example section)

Tests

All classes in the codebase are tested, and you can run those tests by typing:

bundle exec rake tests

Example

An example can be found in example.rb, and it can be run this way:

bundle exec rake example

We use a GPX exported from this Garmin Connect activity which maps the 2015 Granada Half Marathon.

The example is assumed to get that GPX and an input pace of 4:00 minutes per km, which is the theoretical pace for a flat course, and gives the following output:

Example: Granada Half Marathon (from flat surface pace: 4:00 min/km)
Km 1 (incline 1.85%): 04:21 min/km
Km 2 (incline 0.65%): 04:07 min/km
Km 3 (incline -2.7%): 03:33 min/km
Km 4 (incline 0.0%): 04:00 min/km
Km 5 (incline -1.6%): 03:43 min/km
Km 6 (incline 0.53%): 04:05 min/km
Km 7 (incline -1.03%): 03:49 min/km
Km 8 (incline 0.2%): 04:02 min/km
Km 9 (incline -0.4%): 03:55 min/km
Km 10 (incline 2.3%): 04:27 min/km
Km 11 (incline -0.47%): 03:55 min/km
Km 12 (incline -0.31%): 03:56 min/km
Km 13 (incline 1.99%): 04:23 min/km
Km 14 (incline -0.5%): 03:54 min/km
Km 15 (incline 1.47%): 04:16 min/km
Km 16 (incline 0.68%): 04:07 min/km
Km 17 (incline -0.95%): 03:50 min/km
Km 18 (incline 0.5%): 04:05 min/km
Km 19 (incline -1.6%): 03:43 min/km
Km 20 (incline -0.49%): 03:54 min/km
Km 21 (incline 0.19%): 04:02 min/km
Km 22 (incline -0.43%): 03:55 min/km
