I came across this finish-time predictor calculator from another blog. I have to say that I am shocked by how accurate it is.
I inputted my recent 1 mile PR, I then compared it to some of my other PR’s. With one glaring exception, the results are shockingly close…
Based on your 1 Mile time of 6:51, these are your projected finish times:
5K-22:47 (7:20/mile). Actual PR-22:49 (7:21/mile)
10K-47:30 (7:39/mile). Actual PR-47:41 (7:40/mile)
Half Marathon-1:44:48 (8:00/mile). Actual PR-1:44:03 (7:56/mile)
Marathon-3:38:29 (8:20/mile). Actual PR-4:26:15 (10:09/mile)
Clearly, I have work to do on the marathon distance…
