Durable items include toiletries, socks and underwear, and food distribution items. Make sure you’re fully stocked a week before your run.
Each group should put together toiletry kits in advance of the run. Collect travel sizes of the various items (no full-size items), and assemble into kits using gallon size ziploc bags. Some drug stores will sell travel sizes in bulk at wholesale if you explain what you're doing. And Midnight Run can supplement what you're missing.
If you can't assemble full kits, bring what you can. Individual items are welcomed as well, and more appropriate for some. Bring 40 to 60 kits, and some loose items as well.
