I hope someone can help me. I need a detailed form guide which has:-
A horses starting position, mid position and end of race position in its last race as well as the class of its last race. For example, it started at barrier 1, 200m mark was in 2nd position, middle of the race was 5th and finished 1st in a 2YO Handicap race.

And is possible if anyone knows of one that also has trial workout times in its most recent workouts leading up to the meeting.

Any help would be greatly appreciated.
