WATER STATIONS<\/h3>

We recommend all 10K and half marathon runners carry at least 2 bottles or a large hydration pack (or both).<\/p>\n

Rock City: 7.9 (no cut-off)<\/p>\n

5K<\/strong><\/p>\nThe 5K will have an aid station located shortly before the turn around point (about mile 1.1 and then again at mile 2).<\/p>\n
Note: To lower the amount of waste at our Ultra Half Series races, we ask that our half marathon runners (and all runners where possible) be “cupless” during their runs, especially at the half-marathon-only water stations.<\/strong><\/p>\nSince the course and conditions of these half marathon courses already dictate that carrying water bottles\/hydration packs is the best practice, this is usually easy to do. Water station volunteers will be ready to refill whatever container one brings. Runners can also carry reusable cups that easily collapse and can be stuffed into their pockets\/attached. If you wish to purchase a Hydrapak Speed Cup (available for $5 with sales tax), we have those available at our merchandise tent.<\/strong><\/p>\nHalf marathon water stations will not have full cups waiting for runners, but safety is their priority and so if you have nothing and need the fluids, they will get a cup for you.<\/strong><\/p>\n\t\tREGISTER TO RUN<\/h2>\n\t\tJoin us\u00a0 for our epic 5k, 10k, half marathon and 50k trail runs on Mount Diablo!<\/h4>\n\t\t\t\n\t\t\t\t\t\tRegister Today\n\t\t\t\t\t<\/a>\n\n\t\tSPONSORS\n\t<\/h2>\n\t\t\t\t\n\t\t\t\t![\"GU_Logo_4Color600\"](\"https:\/\/brazenracing.com\/diablotrailschallenge\/wp-content\/uploads\/sites\/17\/2016\/05\/GU_Logo_4Color600.png\" "\\"GU_Logo_4Color600\\"")

\n\t\t\t\t<\/a>\n\t\tGPX FILES<\/h3>
Want to follow the course with your phone or smart watch and know how to work with GPX files?\u00a0 You can do that by uploading the race course GPX file (created with “Ride With GPS”) into your favorite app.\u00a0 GPX files are on the course map.<\/p>\n
Important Note: We recommend right-clicking and choosing “save as” to download.<\/p>\n
5K gpx<\/a><\/strong><\/p>\n 10K gpx<\/a><\/strong><\/p>\n Half Marathon gpx<\/a><\/strong><\/p>\n 50K gpx<\/strong><\/a><\/p>\n\t Each course will be marked with colored ribbons, signs, and flour. \u00a0Runners unfamiliar with the courses should carry a copy of the course map to ensure they stay on course.<\/p>\n\t\t Water\u00a0stations will be stocked with water, sports drink, gels, pretzels, candy, etc.<\/p>\n We recommend all 10K and half marathon runners carry at least 2 bottles or a large hydration pack (or both).<\/p>\n 50K<\/strong><\/p>\n Please note: All 50K water stations will be cupless. 50K participants must carry a hydration pack and\/or water bottles.<\/strong><\/p>\n The\u00a050K\u00a0water stations, their distance into the\u00a0race\u00a0and their cut-off times are as follows:<\/p>\n Little Pine: 2.9 miles (no cut-off)<\/p>\n Rock City: 7.9 (no cut-off)<\/p>\n Curry Point: 13 (cut-off = 11:10 am)<\/p>\n Summit: 16.5 (cut-off = 12:35 pm)<\/p>\n Juniper: 23.1 (cut-off = 2:55 pm)<\/p>\n Burma: 27.3 (cut-off = 4:05 pm)<\/p>\n Half Marathon<\/strong><\/p>\n The half marathon will have 4 aid stations (at miles 1.1, 2.8, 7.8 and 12.36).<\/p>\n 10K<\/strong><\/p>\n The 10K will have 3 aid stations (at approximately miles 1.1, 2.8 and 5.1).<\/p>\n 5K<\/strong><\/p>\n The 5K will have an aid station located shortly before the turn around point (about mile 1.1 and then again at mile 2).<\/p>\n Note: To lower the amount of waste at our Ultra Half Series races, we ask that our half marathon runners (and all runners where possible) be “cupless” during their runs, especially at the half-marathon-only water stations.<\/strong><\/p>\n Since the course and conditions of these half marathon courses already dictate that carrying water bottles\/hydration packs is the best practice, this is usually easy to do. Water station volunteers will be ready to refill whatever container one brings. Runners can also carry reusable cups that easily collapse and can be stuffed into their pockets\/attached. If you wish to purchase a Hydrapak Speed Cup (available for $5 with sales tax), we have those available at our merchandise tent.<\/strong><\/p>\n Half marathon water stations will not have full cups waiting for runners, but safety is their priority and so if you have nothing and need the fluids, they will get a cup for you.<\/strong><\/p>\n\t\t Thank you to our race sponsors, through their contributions, our sponsors help keep entry costs down and expose our runners their outstanding products and services.
