If you would like to consider other area hotels, here are a few suggestions: Additional Lodging Options in the Boulder Area

Local Transportation

Boulder is a popular destination in the summer. There are lots of visitors who come and stay as well as those who are just passing through. Traffic in Boulder can be a bear! So, even if you have a vehicle, you might consider alternate transportation for some of your traveling within Boulder. The bus system, RTD, is amazing. Check out the Boulder Bus Routes. The Hop, Skip and Jump will get you around the greater Boulder area.

Bike Rental

Boulder Bcycle stations can be found all around Boulder. This is a great alternative to the bus or the car. Ride along the scenic Boulder Bike Path and see first hand where the athletes will be doing much of their run. The bikes are equipped with baskets to hold groceries and other items.
Alex Bogusky, co-founder of BCycle, talks about how BCycle came to be:

The swim and T1 will take place at the Boulder Reservoir. This is a beautiful venue. Please remember, there will be NO parking at the reservoir on race day. The only access will be to ride the shuttle busses provided by Ironman Boulder. Currently, the only boarding location is Boulder High School at 13th & Arapahoe in Boulder where Ironman Village is located and T2 will take place.

Course Maps

Ironman Boulder Race Director Dave Christen released to 303Triathlon the updated course maps for both the bike and run courses.
View the new course maps here.

In addition to the Ironman staff who plan and organize each Ironman event, it takes 5000 volunteers to man changing stations, water stations, medic stations, course safety, the finish line, and more. If you're interested in cheering on the nearly 3000 athletes that will be racing IMB, sign up to volunteer on race day.

Volunteer Registration


As information is released from IMB we will provide you with as much detail as we can on where to spectate from on the various courses. Please know that there will be NO parking allowed at the Boulder Reservoir or at Tom Watson Park on race day. ALL athletes and spectators will be required to ride on the shuttle busses provided.

Race Director Dave Christen's, comments on parking at Tom Watson Park:
Tom Watson only has 50 parking spots. I agree that it would make sense to just park there and walk over. Here is the problem though, if we say that you will have 3000 people try that. Obviously they cannot do that. They will start to park at IBM, on the roads, wherever they can and it will cause big issues.
Boulder County Sheriff will be patrolling and not allowing anyone to park along 63rd or use Tom Watson that AM. Athletes and spectators alike will be very disappointed if they try as local authorities will shut the attempt down and they will need to head back to Downtown and get on the shuttle. Not the way to start the day.

We discovered a great Athlete Tracker. Read about it here.
