Diablo Trails Challenge offers races for runners of all skill levels

Runners can sign up for 5K, 10K, half marathon or 50K challenge

Tri-Valley runners of all stripes have been invited to test their skills at the devilishly challenging Diablo Trails Challenge this Saturday.

The Diablo Trails Challenge -- which supports the environmental preservation efforts of Save Mount Diablo -- offers opportunities for runners of all levels, from a friendly 5K to the more-daunting 50K challenge, with all courses accompanied by the beautiful backdrop of the area.

“For over 40 years, Save Mount Diablo has worked tirelessly to preserve and increase the open space on and around Mount Diablo,” organizers from Brazen Racing, the event’s sponsor, wrote on their website. “With distances suitable for everyone from those hitting the trails for the first time to experienced ultra-runners, the Diablo Trails Challenge was created to help celebrate and support these achievements. A portion of all entry fees will go to Save Mount Diablo to help them continue preserving open space and trails for all of us to enjoy.”

While courses will vary in length and fee, all races will begin and end at Castle Rock Recreation Area, 1700 Castle Rock Rd, Walnut Creek, will be professionally timed and will award medals after the race. Water stations will also be strategically placed throughout the courses, stocked with water and snacks to help runners refuel.

Experienced runners are invited to test their mettle on the 50K course, which will run through Curry Point up to the mountain’s summit and back to the starting point at Castle Rock Park. The course starts at 6:30 a.m., will have a time limit of 11 hours and cost a registration fee of $125.

The Men’s 50k Challenge record is held by Brett Rivers, who in 2014 was able to complete the course in 4 hours 6 minutes and 21 seconds, the women’s record is held by Magdalena Boulet, who in 2015 made the run in four hours 34 minutes and 22 seconds.

Not to be taken lightly, the half marathon course will start at 8:30 a.m. and will have a time limit of 4.5 hours, a registration fee of $84 will be applied prior to the start of the race.

At 9 a.m. competitors of the 10K course will begin their run, which will cost $63. 5K runners will start half an hour later and be charged a $58 registration fee.

While it is possible that all available spots will be sold out come race day, day-of registration will be allowed -- for an additional $5 -- if space is available. Runners are encouraged to register online beforehand to join in on their chosen competition.
