Are these things she wants to send to you at the resort? If so, because so many things you race with are personal choices and you want to try them ahead of time, my thoughts are these:
Biofreeze - it is my favorite as well. PLUS: if your feet are sore and tired, put it on them before you go to bed at night and your feet will feel refreshed in the morning.
Snacks are always appreciated on a race weekend. Bagels, those little tubs of Jif peanut butter, bars, almonds, fruit leather etc. I personally like instant oatmeal, bowls or mugs and plasticware if you will have a coffee maker (for heating water) in your room and like oatmeal. Hot cocoa packets. Pretzels or cheesy crackers - nice to have something salty both before and after.
Travel size tums.
Lip Balm.
Bodyglide and/or travel size aquaphor.
Inexpensive Plastic Ponchos.
Hand warmers. Nope, I'm not even joking. I would not have gotten through last year's races without those warming things. Inexpensive hats and gloves and scarves are great as well, both for the parks and for the race. The kind that cost $1 are perfect. If she can find them in Lime Green (as I hear are available at Target right now, at least in gloves) so much the better! They make waiting in the corral so much more comfortable even if it's not actually snowing/sleeting. I also like to have a fresh hat and gloves in my checked bag.
This is all the expendable stuff that I try to make sure I've got on hand when I'm racing away from home and especially in cooler temps.
If she's going to give this to you before you leave and after you get home, my answers would be totally different!
