space it out. and leave early. pass slower riders with caution.
generally, LAB2V isn't that bad with the dust. there are just a few sections of powerline roads that are silt/gravel and they're in the morning when a lot of riders are clustered together. it opens up later. keep a good pace and take few breaks and you'll be good.
you are racing daylight, so don't loligag. sunrise is around 6:30AM and sunset is around 4:30PM, but with all the mountains/hills, it's dark by 4:00.
with that said, make sure you headlight/tail light work well.
3 years ago I was in dune buggy/truck woops on the way into Barstow, and the headlight was worthless. sand-sky-sand-sky-sand-sky you get the picture. miles of it.
Day 2 has a section with 17 miles of deep sandwash. deep.
keep you speed up and throttle through it.
