How it works:

1. You register with us! You agree to fundraise at least £150 for NKH Research (£300, for the longer distance) – you can either pay it up front, or add a justgiving page to our team campaign.

2. You’re added to our NKH 100 Mile mission! We’ll email you with everything you need to get started, including dates and app links. You’ll need to download the My Virtual Mission App (available on iOS and Android).

3. The challenge kicks off on the 1st of July – across the month you log your steps, runs, dances (you do you!) on the app, and you’ll see your little icon move along the course.

4. You aim to move 100 miles across the month of July, that’s 7,000 steps a day. You can do it!

5. On the last weekend of July (Saturday 27th July), we’ll do a (completely optional) IN-PERSON walk around Battersea Park, in London. A chance to get some extra steps in!

6. We send all the raised funds to NKH Research, woo!

About NKH

NKH (Nonketotic Hyperglycinemia) is a rare and terminal metabolic disorder in children. It’s rare, there are less than 40 kids living with NKH in the UK. At this point, there is no effective treatment. We’re raising funds to change that.

All proceeds go to the Mikaere Foundation to raise funds to support children and families living with NKH and NKH Research. We’re determined to give our research teams the best shot at finding a cure for NKH.

About Mikaere

Mikaere (or Kai, if it’s easier to pronounce) is a child with NKH. Because NKH is terminal and treatment options are limited every day is precious. His family are doing everything they can to give Mikaere the best quality of life they can.
