Aliy Zirkle is First Into Ruby

Aliy Zirkle, who's managed several top 5 finishes, was the first musher to arrive at the Ruby checkpoint. She'll be taking a mandatory 24-hour layover, along with most of the other leaders.

Martin Buser and Jeff King are both within striking distance, however, and both have plans to regain the lead - of course.
