Orientation & Logistics

Boulder has it all. The place not only astonishes with the Flatirons as a backdrop, but also offers a European style downtown, with Pearl Street as the central axis.

Unlike many other smaller cities in the US, Boulder offers great public transportation networks. Not only is the bus system reliable and affordable, but the city also surprises with a city bike rental, offering e-bikes which can be picked up and dropped off at various points throughout downtown. Both transportation systems are accessible via app (Transit, Boulder BCycle), and allow for uncomplicated and up-to-date information.

The best time to visit is during Spring or Fall. Boulder has a relatively mild climate with lots of sun and low humidity, and offers great outdoor conditions for endurance athletes to train all year round.


If you’re looking for a track to run on, Centennial Middle School Track is the spot. It is located in the north of the city, 15-min by bike from the Downtown. In case you’re staying somewhere south-east of the city, the track at Manhattan School of Arts is easier accessible. Both sports facilities offer a 400m tracks.

Running on the dirt road around Boulder Reservoir further from downtown is worth the trip if you’re looking for a route to do a tempo, long run or easy run with a soft surface to give your legs a break. A loop around the gorgeous lake is 8.5km long and is a must-run during your stay in Boulder. Another great option is running along the Boulder Creek Path, which spans 11 km through the center of town.

If you want to go high and run hard, Magnolia road, also called ”Mags” by locals, is a classic Boulder run. It is a 19 km road that connects Boulder Canyon with Peak-to-Peak Highway in Nederland. The first 6km are paved and average a 9.1% grade, maxing out at 17%. This 13 km section is the ideal place to plot out your workout.

Boulder is consistently rated as one of the best places to bike in the US. The Boulder Valley has more than 500 km of bike way, including 150 km of bike lanes, 135 km of multi-use paths, 80 km of designated bike routes and the network is still growing.


One of the best scenic hill climbs is along the Flagstaff Road. The twisting mountain road begins near the base of the Flatirons, at the Chautauqua Park. The climb to the top is brutal, but the views along the route make it totally worth it. And no worries, there are potential rest points like Panorama Point which offer a stunning view over Boulder Valley. There is the possibility to stop at Realization point and shorten the ride, or continue up to the Lost Gulch Overlook. The ride finished at the Gross Reservoir and is 30km long, perfect for some intense hill reps. Since it’s one of the most busy rides in Boulder, it can get pretty busy in the afternoon, so it might be worth getting up earlier.

Another great cycling route is towards the Left Hand Canyon, a long, sustained mountain climb in Colorado’s Front Range. Beginning in the flats of Boulder Valley, the ride follows the Left Hand Creek, with beautiful views along the Arapaho & Roosevelt National Forest up to the historic mining town of Ward. The climb takes you up to, 2700 m above sea level, so don’t be surprised if you’re more out of breath than usual. Once you’re in downtown Ward, stop at Utica Street Market, a cyclist friendly grocery store to fill up on snacks before you turn back down the canyon. The roundtrip is 52.6km in total.

Another great option for a round trip is the Peak to Peak Highway which connects the town of Black Hawk to the I-70 corridor, Estes Park and Rocky Mountain National Park. Especially if you’re in Boulder during fall, this is a must-do since the colors of the leaves will amaze you. It starts in Nederland (30 min away from Boulder). Then you continue north through Ward and up towards Estes Park, descending into Peaceful Valley. The ride takes you parallel to the Continental Divide, and you can ride up to 96 km one-way. Most people who attempt the full route come with a support vehicle.

Make sure to join Boulder’s Social Rides to meet the locals and explore some more. The weekly business social rides are always on Wednesday morning and offer different routes and groups to join. Furthermore, you can socialize over a great cup of coffee afterwards at Amante’s.

There you can enjoy family recipes that have been passed down to Jay from his great-grandmother who, believe it or not, was the cook for the first King of the United Countries of Italy, Victor Emanuel the Second. It is a casual-dining restaurant that serves authentic home-style Italian-American cuisine. Pro-tip: Try the house-made ravioli for an explosion of flavor.

If you’re not on the bike, but in desperate need of some caffeine, Boxcar Coffee Roasters is a must-try! Easy to find on Pearl Street downtown, It is an awesome place to relax, and recharge. One of the best coffee places in Boulder. Definitely try their flawless espresso.

Another wonderful place with top-notch coffee is Alpine Modern. Luckily, you have two locations to choose from: one on Pearl Street and the other on College Avenue in University Hill.
