EDIT: I think I understood that I need to research "adventure racing" and "ultra running" to get answers to that question. Posting here was probably a little off-topic, sorry.
There's a thread from 2007
about backpacks for running — but in a smaller size, and since things probably changed since then, I thought I'd start a new one.
I've been training for an "orienteering exam" where you need to always have at least 10kgs (22lbs) on your back, which means you leave with 13kgs (29lbs) because of water and snacks over the eight hours of the course.
Although the event isn't about running, in reality you can't make the time gates unless you jog whenever you hit a reasonable trail.
I've been fairly satisfied with the current pack when tightening all the straps (it's a ski touring pack so it doesn't sway too much), but wondering if someone makes a pack that will really stay glued to the back without any sway.
The current pack is a Deuter Freerider Pro 30. That seems to be the right size for the weight and volume required.
Other requirements are:
- hydration hole
- belt pockets for snacks
- ideally, but not necessarily, fairly easy access to stuff at the bottom, because at any time members of the jury can stop you and ask to see a piece of equipment from the required list (e.g. tea candle, physiological serum, tarp of a mandated size… I kid you not).
A vendor suggested the Osprey Talon 33 but I haven't dared to purchase without trying. And on second thought I'm pretty sure the light fabric would get shredded in rough terrain.
Are you guys aware of a make / model of pack that just has an outstanding reputation with runners for staying glued to their backs?
Thanks in advance for any thoughts. :-)
