Watched Secretariat run in person twice before the Triple Crown. The Belmont race was special to me because he ran every quarter faster than the previous one while setting an unprecedented record at a mile and a half at that.
Only one other horse I’ve ever heard of even close to his level was Phar Lap. If you’ve never heard of him take the time to check out his story. Racing commission didn’t want him beating US horses and put outrageous weights on him and he still won. The rest I won’t spoil but it was unreal what they went through.
