1st Place in R-80 Chocobo race rewards you 117 MGP. This is somewhat moderately easy with a Pedigree 2 Chocobo. Can't imagine how high the rewards are when you're first place with a Pedigree 9 Chocobo.... R-500... 1000? 2000?

The reward will scale as you go higher and higher. I think it's important to sink your MGP into something that will get you better returns later. TT or Racing, once you pour in enough the MGP will start rolling in I suppose.
