I saw this tip recently from my buddy Endurance Dave Hanenburg and thought I should share it.

If you’ve ever run with a hydration pack before, you know that the air trapped in the bladder can lead to the pack bouncing around on your back and making an annoying sloshing sound that drowns out all of the sounds around you.

My normal method of solving this is to force out as much air as I can before capping the pack, which works to a certain extent.  Dave, however, has a better method (which he got from Tim Necker):

Next time I run with my pack I’m definitely going to give Dave’s method a try.

What’s your preferred method of getting as much air out of your pack as possible, or is this even something you’ve ever worried about?
