there are two seven furlong distances at Keeneland, one is a straight up 7 furlongs and the other is elongated, its run about 3-4 seconds slower due to the added distance. There is no RDSS correction for this odd ball distance, because it is listed as 7 furlongs, but it distorts early and late info on the TPR screen.
Here is one horse that ran it, but it ran another 7 furlong race at the normal distance.
