Can anybody tell me or do they no, the best web sites to find out the information for the past 5 10 15 and20 years if possible, what was the longest run and average run of consecutive winning favorites, and what was the average prices returned.
Adrian Massey’s site will give you some excellent stats on winning runs of favs.
His stats go back to 1991 I believe, so not quite as far as you were asking, but a pretty long way nevertheless.
Once on his site look for the favourites statistics button, you can choose ‘All Races’ or just 2 or 3 year olds or Handicaps etc. When you’ve decided scroll down to the bottom and you’ll get a table of longest runs of winners and longest runs of losers for that category.
