Expect traffic, esp if going to the range.
Typically, after a certain time, they have the runners on the side of Kalanianaole Hwy, but IDK if this is all race because I've never driven in the morning.
If you're in Kakaako, you won't be able to leave the area until about 7am-ish. I learned this the hard way as I was on the way to a HRA skill builder and was boxed in. I tried going thru Chinatown/downtown, Waikiki (Fort Derussey) and had no exit out of Waikiki. I got to the skill builder late. Another time, I left early as I took my dad to the race, but I was unable to get back into Kakaako. So I went to Zippys to eat breakfast in Kapahulu.
