What is the Run 100k in May Challenge?

Set your pace and make a difference.

Run 100k in May is a virtual fundraising challenge. The goal is simple: to run 100km throughout the month of May. 

You can take it on your way – outdoors, on a treadmill, or a mix of both.

To help plan your month, that’s roughly 25km per week, or five 5km runs per week  but these are just suggestions. You can split your runs however works best for your schedule.

The key is to commit to the challenge and stay consistent, so you can reach your 100k goal by Sunday 31st May 2026.

Whether you’re a seasoned runner or just starting out, join our Run 100k in May challenge to support people living with and affected by diabetes, run on your schedule, your way, and feel your sense of achievement grow.

Sign up for Team Diabetes UK – Run 100k in May and receive:

  • A Free Diabetes UK challenge T-shirt
  • A Free paper welcome letter and progress tracker.                                                               

Once received, use your tracker to log your kilometres each day and see your progress grow. It’s a great way to stay motivated and feel proud.

There is also a chance to earn fantastic rewards along the way!

  • 🧢Raise £50 and we'll send you an exclusive Diabetes UK Cap.
  • 🏅Raise £100 and we'll send you a Diabetes UK medal to thank you for your amazing efforts.

Your Impact: How Your Support Helps.

  • £2 could help someone living with diabetes get answers and advice from other people who understand what they are going through in our Diabetes Support Forum.

My Welcome Pack hasn’t arrived yet. What’s the next step?

If it’s been more than 10 days since you set up your fundraising page, and you’ve registered and received a welcome email from us, but still haven’t received your pack please get in touch.

You can message us in the Facebook Group or email us at Facebookchallenges@diabetes.org.uk.
Be sure to include your full nameemail address, and the date you registered so we can help you as quickly as possible.

What happens if I can’t complete the challenge due to illness and can no longer take part?

If you or your family members feel unwell or are unable to continue at any point during the challenge, it’s important to prioritise your health and seek guidance from a medical professional.

You can pause your challenge, adjust your distance goal, or resume at a later time, whichever works best for you, so you have the chance to rest and fully recover while still participating safely.

How can I share safely online?

We love seeing your photos and updates from your 31 Miles in August challenge
Sharing your journey can inspire and connect us all but it’s really important we keep everyone safe too.

Here are a few simple tips to help:


Ask first: Before sharing a photo or story that includes someone else (especially a child), check you have permission from a parent/carer.
Everyone should feel comfortable with what’s shared about them.


Think before you post: Once something is online, it can be copied or shared beyond your control  even in private groups.
Take a moment to decide if you’re happy for it to be seen more widely.


Keep personal details private: 

Avoid sharing things like:
Full names
School or location details
Regular routines
Small details can sometimes add up and identify someone.

 

Be mindful of tagging: We recommend not tagging children in photos, to help protect their privacy and safety.
