GDGC Datathon 2025 - Formula Racing Lap Time Dataset

Dataset for predicting Formula racing lap times, used in the GDGC Datathon 2025 competition.

Dataset Description

This dataset contains historical Formula racing data with various features related to circuits, weather conditions, rider/driver performance, and race configurations. The goal is to predict Lap_Time_Seconds.

Target Variable Statistics

Metric	Value
Count	734,002
Mean	89.997 s
Std	11.532 s
Min	70.001 s
25%	79.989 s
50% (Median)	89.970 s
75%	99.914 s

The target distribution is nearly symmetric with mean ≈ median, indicating no significant skew.

Usage

Loading with Pandas

import pandas as pd

# Load training data
train_df = pd.read_csv("train.csv")
print(f"Training samples: {len(train_df)}")

# Load test data
test_df = pd.read_csv("test.csv")
print(f"Test samples: {len(test_df)}")

# Separate features and target
X = train_df.drop(columns=["Lap_Time_Seconds", "id"])
y = train_df["Lap_Time_Seconds"]

Loading from Hugging Face

from huggingface_hub import hf_hub_download
import pandas as pd

# Download files
train_path = hf_hub_download(
    repo_id="Haxxsh/gdgc-datathon-data",
    filename="train.csv",
    repo_type="dataset"
)

test_path = hf_hub_download(
    repo_id="Haxxsh/gdgc-datathon-data",
    filename="test.csv",
    repo_type="dataset"
)

# Load into pandas
train_df = pd.read_csv(train_path)
test_df = pd.read_csv(test_path)

With Datasets Library

from datasets import load_dataset

dataset = load_dataset("Haxxsh/gdgc-datathon-data")

Trained Models

Pre-trained models for this dataset are available at:

• Models: Haxxsh/gdgc-datathon-models
• Training Code: ezylopx5/DATATHON

Evaluation Metric

The primary evaluation metric is RMSE (Root Mean Squared Error):

from sklearn.metrics import mean_squared_error
import numpy as np

rmse = np.sqrt(mean_squared_error(y_true, y_pred))

Data Preprocessing Tips

1. Handle categorical features: Use label encoding or one-hot encoding for columns like weather, circuit_name, Tire_Compound
2. Feature scaling: Normalize numerical features for certain models
3. Missing values: Check for and handle any missing values appropriately
4. Feature engineering: Consider creating interaction features or aggregations
