I have been using a pack for running from RaidLight for the past 6 months. After running in The Atacama Crossing I have reevaluated my needs for a better pack. The RaidLight is a great pack but it is a little to large. The axiom that no matter what size pack you get you will fill it up to the top with “stuff”. So I have moved to a new pack from Inov-8. For my next race (Racing The Planet Sahara?) I am planning on using the Race Elite 25. I took it out for a 10 mile run this weekend and it seems to meet my needs.
I am working on a new packing list for expedition type running races. Hopefully I will have a new photo of what I am packing based on my in-field experience of running The Atacama Crossing.
