Hey friends, we really need your input on something...

Usually its not hard for us to talk about our event and what it means to us... but this time we were asked to talk about what makes the Thunderhawk Wide Open a success for our community and its participants.

Its funny... but it took a little too long to figure out why I was struggling to answer this question in a way that felt authentic... but eventually, I realized that the best people to answer this question isn't us, its you: our guests, and friends, and amazing supporters.

So, We would really like to hear from YOU. Are you a Lemmon community member? or a past TWO participant? What made the TWO a success for you?

If you are maybe a little shy like us and dont love PDA we completely understand, you can totally send us a message if you want, lol.

thanks!

Hey bicycle friends, thought it was time to dust off the ‘ol instagram to let you know we are busy working on some exciting changes for the TWO for 26….

We should have registration up within the month. Until then we hope you all are enjoying the winter landscape and having a great start to the new year.

Talk soon!
