The 2025 London Marathon is getting closer and closer (it falls on April 27 this year), and many have been training for the big run months in advance.
While many have prepared for the marathon, we can’t always plan for our periods, but WUKA aims to change that to ensure women aren’t caught out this weekend – or at any point during their cycle for that matter – with the launch of its new Perform Period Shorts.
These innovative cycling shorts have been specifically designed to empower women to run with confidence, regardless of where they are in their menstrual cycle, and to combat any leakages during the 26.2 mile run.

Perform Period Shorts
These cycling shorts are not just any cycling shorts, they double as period underwear too. This hybrid design has been crafted from recycled nylon, and is chafe-free for an ultra comfortable fit. The crucial part of the design is these shorts offer medium absorbency; it can hold up to 15ml of fluid, which is the equivalent of two to three tampons or four sanitary towels.The leak proof gusset ensures no leakages are visible for your protection and comfort. The smooth shorts also offer no VPL, which provides extra comfort and are great for layering underneath other layers too. Available in extra small to 2XL.
BUY NOW FOR £48With over 50,000 runners expected to flood the streets of London, WUKA is addressing a barrier many female athletes battle in silence: menstrual disruption.
WUKA has shared some studies with us that show 78% of girls avoid sports while on their period, while 69% of women modify their workouts due to symptoms, and a staggering 88% feel their performance suffers at different stages of their cycle. WUKA’s new launch aims to provide both performance and protection for women facing the all-too-common challenge of managing their period during athletic events, which we think is simply genius (and long overdue).
Speaking about the new launch, Ruby Raut, WUKA’s Founder and CEO, said: ‘We designed the Perform Period Shorts to help women feel confident, protected, and unstoppable, whether you’re training for race day or crushing 26.2 miles through London. Running a marathon is about pushing limits. Your period shouldn’t be one of them.’

The Perform Period Shorts offer medium absorbency, as it can hold up to 15ml of fluid, which is roughly the equivalent of two to three tampons or four sanitary towels. The design includes a mid-thigh cut with seamless edges to prevent any chafing on an already sensitive body, and a leak-proof gusset. The Invisi-Fit finish provides a smooth, discreet silhouette under running gear, while two discreet side pockets are ideal for athletes to carry any essentials, such as water, electrolytes, a phone, or headphones. These shorts are also made with sustainability in mind, as the Perform Period Shorts have been crafted from recycled nylon that replaces up to 200 disposable period products.
We have tried WUKA’s period underwear and can attest to its reliability, so we are impressed to see the new iteration hit the virtual shelves in time for marathon day.
Whether you’re racing in the marathon, or have been inspired to pound the pavements and tackle your first 5K, WUKA’s Perform Period Shorts have you covered – in more ways than one.
Available online for £48.99, which we think is a reasonable sum for the protection these shorts will offer, and support throughout your cycle, month after month.
