boobydoo are the UK’s Sports Bra Experts who specialise in properly fitting sports bras, and provide women with the support they need to tackle their exercise goals without having to worry about their boobs! We’re teaming up with boobydoo to bring you this special January challenge in the year that boobydoo turns 21 years old, all whilst offering you advice, deals and fitting tips about sports bras along the way.
This challenge is open to everyone and you can run, wheel or walk your way to 21km (21k for 21 years, see what we did there?!) between 1st – 31st January 2026 to earn your exclusive bling! The mileage doesn’t need to be done in one go, but you can of course if you’d like! The results table will work on total mileage for January, so the more you do, the higher up the results table you’ll climb.
We only require one submission of evidence so please upload once you complete the challenge. You must submit a minimum of the half marathon distance (21k).
The deadline for submissions is 3rd February 2026 at 12 noon, failure to submit ahead of this time will result in you not receiving your medal.
The race charity is The Teen Project and they will receive a minimum of 20% of every entry fee.
