A bit of advice from someone who did these a LOT, haha! 
I don’t think I had any in-person competition last few events of this for any I raced for, maybe once IIRC But this is an event to seriously consider getting a rental for - reason is, unless they changed it, other people completing meteors on a world will lower the timers for everybody.
You really don’t want to complete Gleambow meteors. Yes, you get Oort, but you’ll eventually drive the timers down to like 30 seconds completing them, where if you don’t complete them you can drive the timers up to like 2 min IIRC. That is HUGE because the thing you really want to do with them is kill the Gleamtrunks to get sacs to summon more Gleambows! You can get a lot if you get your timers up high. And you can still get some of the blocks without completing them, you might have to test a bit to get the feel but I would take a few hits with a 3x3 and be fine. But might not want to risk it for materials you don’t want.
Take a lv 3 lush, keep the picks as flat, treeless, and water free as possible; reason a rental is good here too is none of the permanents is really ideal for this. I’d sometimes beat the meteors to the spots on my rentals. 
If you get a rental, save the location of each region center, then run between those markers on your rental, hitting the center area will set one off though usually not the first region center you hit when you warp in, for some reason.
