Our annual “Let ‘Em Know 5K” is coming back – a virtual event that brought together people from all over the country! For the past two years, this event to raise awareness and funds for Fragile X has been growing, and now is the best time to join us!

Here’s what you need to know:

What is the NFXF Let ‘Em Know 5K?

The NFXF Let ‘Em Know 5K is part of July’s National Fragile X Awareness Month “Let ‘Em Know” campaign!

The 5K is a virtual run/walk to help raise awareness and funds for Fragile X from anywhere in the world! Ask anyone who’s participated: This is one of the easiest ways to raise awareness for Fragile X, so why not give it a shot?

It isn’t about how fast you are. It’s about what you can do to raise awareness and “Let ’Em Know” about Fragile X.

What does “virtual run/walk” mean?

It means you can complete it anywhere and at any time during the month of July, which is National Fragile X Awareness Month. You can run or walk (or skate, whatever you like!) the 3.1 miles (5K) all at once or over the course of a week or the entire month.

imageIt’s on the honor system—you do not have to report or verify your miles! But we’d love to hear about your run/walk through social media. (More info on that below.)

Registrants will receive a custom-designed, collectible athletic race shirt and NFXF Let ’Em Know 5K race bib.

Not interested in running, walking or strolling?

We’ve got you covered! You can create a fundraising page for no cost and still be entered in the prize drawings! (Sorry, though, only run/walk entrants receive the official race shirt and bib.)

Did we mention we have prizes?!

We have two Grand Prizes* this year. One for the most money raised and one for the greatest number of donations. Each winner will receive a $250 Amazon Gift Card!

Each individual personal fundraising page under the NFXF “Let ’Em Know” event on Crowdrise from now through July 31 will automatically be eligible to win.

Here is what you need to do to get started today… the sooner, the better!

Please check with your doctor regarding your ability to physically participate if you have not regularly exercised in the last 12 months prior to the NFXF Let ‘Em Know 5K. Your doctor will probably suggest there is no time like the present to start getting active!

But be smart, don’t stress and stay healthy—we want you running or walking for Fragile X for a long time to come! All donations to your personal fundraising page benefiting the NFXF on the Crowdrise website are tax-deductible!
