Patent ID: 6909671

Claim:
A computer-implemented predictive method for determining a race finishing time, RFT, while a runner is running a race, including the steps of: (a) setting a race total distance quantity, TD; (b) setting a split distance increment, SDI; (c) actuating a running timer mechanism, outputting an elapsed time quantity, T; (d) inputting a split number quantity, SN, upon reaching a split distance increment, SDI; (e) computing a split time, ST, for each split number quantity, SN, at each split distance increment, SDI, based upon the elapsed time quantity, T; (f) calculating an average split time, AST, based upon the elapsed time quantity, T, and the split number quantity, SN; (g) setting a most recent split time, MRST, equal to the split time, ST; (h) calculating a predicted split time, PST, based upon at least one of the average split time, AST, and the most recent split time MRST; and (i) predicting the race finishing time, RFT, based upon the total distance quantity, TD, the split distance increment, SDI, an elapsed time quantity, T, the split number quantity, SN, and at least one of the predicted split time, PST; and the average split time, AST; wherein the race finishing time, RFT, is determined without the input of any runner physiological data.
