Due to COVID-19, we have capped the race at the moment and opened a waitlist for those wanting to register. This way you can still sign up, but do not have to pay upfront. We will then invite runners off the waitlist to register.

Guidelines for RDL 2020
Due to the COVID-19 in 2020, NorCalUltras has removed the requirement for having completed an official 50M or better event. But, to be able to successfully run and complete Rio Del Lago 100 Miler, it is HIGHLY recommended that you have completed at least one 50 miler run (whether it be a race or in training) before October 25, 2020. And it is also suggested that you finish your run within an official time from any other event. For example, American River 50 has a 14 hour limit. This is in addition to your normal training. We are recommending this to help you get to the finish line. Remember, this is a 100 miler and will tax your body tremendously! Good luck!!
