EndurancePy

Access endurance racing timing & results data in Python — the way FastF1 does it for Formula 1.

---

What is EndurancePy?

EndurancePy is a Python package that aims to make endurance racing data as easy to analyse as FastF1 made Formula 1 data. It loads and exposes timing and results data — lap times, sector times, stints, pit stops, classifications, positions (overall and per class), weather and flag/track status — as convenient, pandas-based objects, primarily from the publicly available Al Kamel Systems timing archives.

Inspired by FastF1. EndurancePy deliberately mirrors FastF1's design and API surface (get_session(), Session.load(), Session.laps, Session.results, pick_* filters, an on-disk cache, a plotting helper module, …) so that anyone familiar with FastF1 feels at home. EndurancePy is an independent project and is not affiliated with FastF1, the FIA, the ACO, IMSA, Al Kamel Systems, or any championship.

Target championships

Series	Full name	Timing source
WEC	FIA World Endurance Championship	Al Kamel
ELMS	European Le Mans Series	Al Kamel
AsLMS	Asian Le Mans Series	Al Kamel
LMC	(Michelin) Le Mans Cup	Al Kamel
IMSA	IMSA SportsCar Championship	Al Kamel (imsa.results.alkamelcloud.com)

Good news for the implementation: all of these series are timed by Al Kamel, so a single parser can cover them all — only the base host and minor URL details differ.

Status

🟡 Alpha. The core works end-to-end (verified against the live portal): sessions, laps, results, schedules, weather, track status, plotting and standings. APIs may still change. Contributions welcome (see Contributing).

The first goal is explicit: offer the same content as FastF1 wherever the underlying data exists. Two structural limitations are known up front: endurance racing has no public car telemetry (no speed/RPM/gear/throttle/ brake/GPS streams) and no normalised historical database equivalent to Ergast — everything else (calendars, sessions, classifications, laps/sectors/ stints/pit data, weather, flags) is within reach from the public timing archives.

Install

pip install endurancepy            # once released on PyPI
pip install "endurancepy[plot]"    # with the plotting extra (matplotlib)
# from a checkout:
pip install -e ".[dev]"

Usage

The API mirrors FastF1, with an added series axis (several championships coexist). Today, a session loads from an Analysis CSV (path, bytes or URL); automatic discovery of remote files is not implemented yet.

import endurancepy as ep

ep.Cache.enable_cache("./endurancepy-cache")

# Load a session from an Analysis CSV
session = ep.get_session(2024, series="WEC", event="Le Mans", session="Race")
session.load(source="path/to/23_Analysis_Race.CSV")

# Classification (per car / per class)
session.results
session.results.pick_classes("HYPERCAR")
session.cars                  # car numbers in finishing order

# Laps
laps = session.laps
laps.pick_cars(["7", "8"])
laps.pick_classes("LMGT3")
laps.pick_drivers("Kamui KOBAYASHI")
fastest = laps.pick_fastest()

# Derived side data
session.track_status          # green / FCY / SC / code 60 / red

See the usage guide, the plotting gallery and runnable examples/ (scripts + a Jupyter notebook) for more.

Roadmap

• Inventory FastF1's full content and API surface
• Map FastF1 features → endurance data availability (Al Kamel)
• License & project groundwork
• Al Kamel client + two-stage cache
• Analysis CSV parser → Laps (+ pick_* filters)
• SessionResults (per car & per class), derived from laps
• Track-status timeline (flags / FCY / SC / code 60)
• Session.load from a file/bytes/URL + parsed-laps caching
• Weather CSV parser + result-file discovery (verified formats)
• Race Classification CSV parser → SessionResults
• Auto-discovery: Session.load(season=...) finds & downloads the files
• Event / EventSchedule + list_seasons (browse seasons; year auto-resolves)
• plotting colour helpers (by class / manufacturer)
• Championship standings (configurable points calculator)
• Docs, tests, packaging & PyPI release
• 0.3.0 — plotting: chart helpers (strategy, race trace, pace…), colour/style system, lap-time axes, track-status overlay

See ROADMAP.md for the detailed plan and the plotting library evaluation.

How it relates to FastF1

FastF1	EndurancePy	Notes
fastf1.get_session()	ep.get_session(..., series=...)	+ series axis
Session.load()	Session.load()	downloads & parses Al Kamel files
Session.laps (Laps)	Session.laps (Laps)	+ Class, CarNumber, Manufacturer, PositionInClass
Session.results (SessionResults)	Session.results	per car/crew & per class
Lap.get_telemetry() (Telemetry)	—	no public endurance telemetry
fastf1.Cache	ep.Cache	on-disk cache (essential for 24h races)
fastf1.plotting	ep.plotting	colours by class/team/manufacturer
fastf1.ergast	ep.standings (later)	rebuilt from results

Contributing

EndurancePy is an open, community project and contributions are welcome — whether it's code, documentation, test data, or simply reporting which series / seasons you'd like to see supported.

Please read CONTRIBUTING.md to get started, and note that all participation is governed by our Code of Conduct.

A good first step is to open an issue describing what you'd like to work on.

Data sources & legal note

EndurancePy is built around publicly published endurance timing archives (Al Kamel Systems results portals; official championship sites such as fiawec.com, imsa.com). It is an unofficial, community project for analysis and research purposes.

• All championship names, logos and data remain the property of their respective owners (FIA, ACO, IMSA, the championships, and Al Kamel Systems).
• Al Kamel Systems explicitly asserts ownership of its timing data and warns against redistribution without consent. EndurancePy is therefore designed to download and parse data for personal/research use only — it does not bundle, ship, or republish any raw timing archives. Please do the same.
• Always respect the terms of service and robots.txt of any site you fetch from, and be considerate with request rates (the built-in cache exists partly for this reason).
• This project is not affiliated with, endorsed by, or associated with any of the above organisations.
