Would you challenge a Northern fur seal to a race? If you've been reading the Fitness Friday posts, you know that a team of Aquarium staffers and friends did. This team is training for the Tough Mudder competition, and they challenged the Northern fur seals to various races and tests of coordination and endurance.

In last week's post, a staffer went up against Cordova the fur seal in a triathlon of crawling, swimming and climbing.

In the video below, you can watch another team member compete against Ursula the fur seal in an obstacle course race that includes water, hoops and limbo poles.



The Tough Mudder team posts updates about their training and you can donate to help them raise money for the Aquarium here.
