Ran my first 10k today. Did a nice first 5 miles in 55 minutes and then in an exhausted state walked the rest (1.55 miles) to bring it to a total of 77 minutes for 6.5 miles. Calorie count 1002 burned. But i feel good, exhilarated!
making adjustments to my 10K (i.e. 6.25 actual miles) that should have set me at 55+18.33 = 73.33 minutes or 1 hour and 13 minutes approximately. That means my average speed was 5.11 MPH (i.e. 60 x 6.25 / 73.33). Not bad for a first timer!
