'NH' & 'Flat' race categories

[thunderfoot]

I've used 'Masseys' data and identified 2 'systems' that have each given even & consistent profits over the past 5 years, but the 2 'systems' are based on different race categories as defined by 'Massey' i.e. National Hunt & Flat. I want to use the daily race cards that are freely available on RacingPost, BUT how do I identify, from the information on RacingPosts race cards (see example below), which is a 'National Hunt' and which is a 'Flat' race.

Re: 'NH' & 'Flat' race categories I am sure someone with more knowledge will tell you, I know zip about horseracing. But I am assuming the (A.W) means ALL WEATHER and as such will be flat?
