chapter challenge stakes versus group and listed stakes

twice a year ONLY GOLD CIRCLE NATAL host 3 chapter challenge races ,,,the stakes per race is 150 000 rand and lets be honest they attract horses that are basically hard knockers who are below group or listed potential ...the problem i have is that the stakes for these races are more and equal to some of the group and listed races held in natal...surely in any sport you should b be rewarding the better performers?if the stake for a chapter challenge race is 150k then a listed race should be 200k etc...this situation doesnt say much about how racing is run in natal

Was trying to get my head round these races,do you have to qualify for entry?

There was a Grade 2 with 200k prizepool the other day..
