[Closed] Gravity Enduro

Anybody on here entered any of the Gravity Enduro events?

Looking to enter my 1st MTB race and as I don't have the time to deticate to xc fitness or DH racing madness (and fitness I know) I'm thinking of the above. I'm comfortable doing DH runs but still a bit abrehensive with big drops and air time but currently only getting out 2, sometimes 3 times a week. Just upped my game by getting out with some new guys who do a bigger loop and ride local DH trails so the disipline is there for technical sections.
If anyone one has done one or does them, could you recomend a fitness programe like what area to consitrate on and or any training schools and any other info.

Thanks guys.
