# Cycling at the 2024 Summer Paralympics – Women's time trial C4–5

The women's time trial class C4-5 track cycling event at the 2024 Summer Paralympics took place on 29 August 2024 at the Vélodrome National at Saint-Quentin-en-Yvelines . This combine class (C4-5) under classification C is for cyclists who have impairments that affect their legs, arms, and/or trunk but are still capable to use a standard bicycle. 13 cyclists from 10 nations compete in this event.
The classifications are described as follows:
* C4: mild hemiplegic or diplegic spasticity; mild athetosis or ataxia; unilateral below knee or bilateral below elbow amputation, etc.
* C5: mild monoplegic spasticity; unilateral arm amputation (above or below elbow), etc.

## Competition format

The competition begins with a qualification round, where the 13 cyclists will compete in pairs against the clock. The fastest six cyclists will qualify to compete for gold, silver and bronze in the final that afternoon, setting off in reverse order sixth fastest, then fifth fastest, etc.. The distance of this event is 500m.
A cyclist may have a different 'result time' than their real-time due to this event being a combined class event (C4-5), and some cyclists in their own class may have a disadvantage over other classes (for example due to speed), thus athlete factoring is used.
Despite this, different classifications have their own world and paralympic Games records

## Background

Double Paralympic Games champion, World record holder and three-time World champion in the C4 event, Kadeena Cox returns to attempt to complete a hat-trick of time trial championships at the age of 33. She arrives off the back of a difficult year that included a series of injuries and a relapse in her Multiple sclerosis condition, but also as the reigning world champion in her C4 category, and with no 'divided loyalties' as Cox was not selected for the athletics squad on this occasion. Her nearest current rival, the Dutch C5 World champion Caroline Groot, now 27, also makes the start line, as does multiple world and Paralympic C5 medalist Nicole Murray of New Zealand. The time gap between Cox and Groot in the 2024 World championships - approximately 3 tenths of a second - means that factoring may have a crucial role to play in the final results.

## Results
### Qualifying

The C4–5 500 m time trial is a multi-classification event. To ensure fairness, factoring is applied to the times of each cyclist based on their classification, and it is this factored time represents their result, both in qualification and, if that cyclist qualifies, the final. In a women's C4-5 track event, the factor for a C4 rider is 98.67 and for a C5 is 100.00. The result of the cyclist is calculated as a percentage of the elapsed time, with the factor providing the relevant percentage.
The six fastest times after factoring qualify for the final.
