Here are 11 metric century rides (aka, a normal century ride to everyone else in the world) that will get your blood pumping, quads sweating and allergies?fully activated.
Tour de SummerlinApril 16, 2016, in Las Vegas, Nev. 1 of 11
While Vegas isn't the ideal place to immerse oneself in blooming flowers and mounds of pollen, it remains the biggest adult playground in the world. Summerlin, the scenic community where the ride takes place, is just a hop and skip from downtown Vegas. While you won't see colorful flowers or The Mirage on your ride, the scenic roads and gorgeous mesas are more than worth pedaling for 100 kilometers.
Burnsville MetricApril 30, 2016, in Burnsville, N.C. 2 of 11
A casual, well-supported ride through beautiful Burnsville, North Carolina, the Burnsville Metric lies next to Pisgah National Forest and in the shadows of Mount Mitchell—the highest peak east of the Mississippi River. This event is perfect for those seeking views that don't require too much work. Despite a course that winds through mountains and valleys, the course is mostly flat.
Rampart Rager 100May 7, 2016, in Colorado Springs, Colo. 3 of 11
Colorado in May? You shouldn't think twice about signing up for this challenging but majestic metric that goes through some of Colorado Springs' most prominent and picturesque places. You may also want to bring your gravel grinder for this one, as 80 percent of the course is dirt.
Natchez Trace Century RideMay 7, 2016, in Ridgeland, Miss. 4 of 11
This is the kind of ride that puts the "hospitality" in "southern hospitality." Hell, it puts the "southern" in it, too. This event is not so much a grueling test as it is a fun spring day on the bike. The race includes stops every 10 to 15 miles that feature local music, food and hands-on fun, and an after party with more food, more music and more fun. Mardi what?
New Mexico Law Enforcement Memorial RideMay 7, 2016, in Albuquerque, N.M. 5 of 11
While the ride is sure to test your fitness and stamina, each difficult mile is a tribute to fallen law enforcement officers. Traveling 100 kilometers from downtown Albuquerque to the New Mexico State Law Enforcement Officers Memorial in Santa Fe, New Mexico, this event is held in honor of nearly 200 New Mexico officers who have died in the line of duty.
Tour of Long BeachMay 14, 2016, in Long Beach, Calif. 6 of 11
One of the largest cycling events in Southern California, the Tour of Long Beach raises over $100,000 annually to support pediatric cancer programs. The event offers cyclists the chance to ride along the beautiful California coast on what should be a perfect spring day in May. You'll ride from Long Beach to Seal Beach to Newport Beach and back.
Tour de LincolnMay 14, 2016, in Lincoln, Calif. 7 of 11
A short drive from Sacramento, this ride in Lincoln, California, traverses a route that utilizes well-stocked rest stops and SAG support as you cruise through beautiful valleys and suffer on challenging climbs. The metric century also includes 3,800 feet of elevation gain, so prepare to tell your legs to shut up around kilometer 80.
San Diego Century Bicycle TourMay 21, 2016, in San Diego, Calif. 8 of 11
This bicycle tour offers various routes, but don't expect novice riders to tackle the 33-mile course. All rides require participants to traverse San Diego's famous hills and demand good fitness and bike handling. Despite the difficulty, stunning views and perfect weather have made the San Diego Century an annual staple in the self-proclaimed "America's Finest City."
Viking Tour 2016May 22, 2016, in Poulsbo, Wash. 9 of 11
The Viking Tour takes place during the town's iconic VikingFest carnival, so don't be afraid to wear your horn-clad helmets on this scenic metric century. The ride finishes in Norway, or (ahem), Poulsbo, Washington—not that you would notice any difference between this charming town and the real Scandinavian country.
Tour de Fronds XIXJune 18, 2016, in Powers, Ore. 10 of 11
Seeking that perfect weather before the sultry summer creeps in? The Tour de Fronds in Powers, Oregon grants riders the challenge of the roads with the charm of the Pacific Northwest. You'll see gorgeous wildflowers, waterfalls, rivers, streams and mountain vistas all through your sweat-filled sunglasses. New to this year's ride, the Tour de Fronds offers two metric centuries—one on paved roads and the other on gravel—so pick the one that most suits your fancy.
