Grizzly 100 & Big Bear MTB Gran Fondo

September 24 @ 8:00 am - 5:00 pm

A truly famous or infamous (depending on the person) race, the Big Bear Mountain Bike Gran Fondo and the Grizzly 100 is a Saturday spectacular of multiple mountain bike race lengths held in the gorgeous area of Big Bear Lake, California. Once two separate mountain bike events, the Grizzly 100 and the MTB Grand Fondo, are now joined into one day of non-stop pedaling. Starting with the route MTB Gran Fondo, which can be categorized as spot climbs with multiple categories allowing for almost every level of rider to enjoy the event and race. There is a 20 kilometer, 30k, 40k, 50k, and 100-kilometer option for the Fondo. The 100k fondo is a ‘rider to recovery’ event aiding veterans recovery which is an extraordinary addition to the Saturday. Then there is the beast of the Grizzly 100 and 75. The Grizzly has gained international recognition as being a spectacular and physically demanding endurance mountain bike race that spans across some of California’s best single track and double track, climbing thousands of meters while all taking place at a hypoxic altitude of up to 8,500 feet! The Grizzly 100 and 75 is the finale race of the National Ultra Endurance Race Series (NUE) in 2021, making it a physically challenging venue to end on and sure to bring some heavy-hitting riders. There are 8 categories in the Grizzly 100/75 that all attribute points to the NUE series. For the 100k and 75k routes, there are single speed categories as well as a masters (50+) age grouping for men and women. Beyond that, for the 100k and 75k routes, respectively, both have a men’s and woman open category. The Grizzly course is absolutely no joke, and the dreaded Radford Climb has been voted as “one of the most dreaded 5 mile climbs in California.” (NUE) There are top of the line aid stations that are more than just fully stocked, great local fans, and amazing participants and volunteers. The Big Bear MTB Grand Fondo and The Grizzly 100/75 is not only one of California’s top mountain bike events, but also one of the top MTB occasions in the United States. Strambecco could not recommend this weekend more; a truly amazing event.
