    The Alpine Runners of Lake Zurich proudly present the 46th Annual Lake Zurich Alpine Races! The Alpine Races 5k and 10-mile courses are USATF certified. The races run through the streets and along the shores of beautiful Lake Zurich. Gatorade and Water will be available along the course. No dogs, strollers, bikes, or rollerblades are allowed in the races please. Keeping with the Race Industry standard, the Alpine Races will not issue refunds or defer for registration made online, by mail, or on race weekend.

    The Alpine Runners 10 Mile Run is a 2026 CARA Racing Circuit Race.

    Volunteers are the backbone of every successful race and we are grateful for ours. But we need even more people to help us with packet pickup, the water stops, and the finish line! Please consider volunteering a few hours of your time on race day. You won't regret it.
