Michigan Bicycle Law is coming in as the Michigan Gravel Race Series Ultra Course Series sponsor, which includes the brand new 100 Mile at this year's Thunder Bay Thriller - Gravel Race 🤘

As a cyclist, what is a phone number you never want to call, but if you must call it, you are darn glad that someone will answer????? In 2016 MGRS board member, Donut Dan, was hit by a car that turned left in front of him and became a member of the “club that nobody wants to be a member of”. Dan made the call to Michigan Bicycle Law and fellow cyclist and advocate for bicycle safety, Bryan Waldman, was there to answer it.

Being a MGRS Ultra Course racer means that you are ready to tackle races of over 100 miles in a single event. Cycling is constantly on the mind of an Ultra racer and we could not think of a better sponsor for the MGRS Ultra Course Series than Michigan Bike Law.
