PDC-Utils

Utilities to manage power duration curves

Fitting algorithm for running or cycling power data with support for Garmin FIT files

Install

pip install PDC_Utils

How to use

Uses a MMP curve based on best power efforts. You can load data from CSV files or directly from Garmin FIT files.

Using CSV data

An example of CSV input is in the data directory:

df = pd.read_csv("../data/mmpcurve.csv")
pdc = PDC(df['Secs'], df['Watts'])

result = pdc.fit()
result.best_values['ftp']

247.97104270072407

Using FIT files

You can also load data directly from Garmin FIT files:

# Load a FIT file and create a PDC object
pdc_from_fit_file = pdc_from_fit('path/to/your/activity.fit')

# Or create an MMP object
mmp_from_fit_file = mmp_from_fit('path/to/your/activity.fit')

# You can also work with the raw FIT data
fit_loader = load_fit_file('path/to/your/activity.fit')
power_data = fit_loader.extract_power_data()
durations, mmp_powers = fit_loader.compute_mmp_curve()
