I wear arm warmers cycling more often than I do running. That's just kind of my preference. Cycling, I'll want a tighter cuff to keep the wind out, so I usually can't push the sleeves of my long sleeve jerseys up to my elbows when it warms up, so if I expect to want bare arms, I'll start with short sleeves and arm warmers. Running, if I push arm warmers down to my wrists, it creates a lot of bulk when I swing my arms, so I'm more likely to start with long sleeves and push them up. But I do have a pair of Pearl Izumi merino arm warmers that are plenty comfortable and warm. I do love my wool.

Possibly ... but more likely to be a lot warmer by the time you finish. That would be something to look at - hourly temperature history for Nara, so you'll know what part of the day is usually warmest - and also, information about the course, whether there's anything particular you can expect about the temperature and/or wind, either particular trouble spots, or how the weather typically changes over the time you'll be running.

What an exciting trip!
