Looks like SANS has partnered with the US Cyber Challenge to launch
CyberAces. A free 9 week long training course/challenge. The courses are open to all, not just limited to students like some of the past US Cyber Challenges.
Looks like there are scholarships in the offering for the top performers as well. ->
Academies | Cyber Aces | Free online cybersecurity courses
Unfortunately registration for the current challenge is no longer open, but I would expect a Spring offering to follow.
