I always bring a running first aid kit with me. Regular and blister band aids, gauze pads, non-cling tape, arnica gel and antibiotic ointment. A friend wiped out badly during a RD race at WDW once and she and her SO had a hard time finding supplies to treat her knees. I keep it all in a packing cube and check it before each race trip. I also put in other running gear- KT tape with scissors and cheap hand sanitizer for application, body glide, etc. A foot massager, stick massager, fuel, bib safety pins, waterproof phone case, earbuds, ice packs and extra running hats also come with me.
One quirk of mine is that I always want to have ID, a credit card, my med/allergy info card, insurance card, hotel key card, and a $20 with me, just in case. I bought one of the lanyard pouches and cut off the lanyard attachment. The cards and money go in the pouch and into the zipped pocket of my running skort. That way they're safe and don't get all sweaty and gross.
