A month ago I ran a crowded 10 km race.
Had to zigzaw myself thru the crowd. Not fun.
Anyways, I went thru the 2nd half of the race in 18.30 min and I am wondering how much I cud possibly expect to run a 5 km?
Is it fair to detract a minute? 30 sec? Or even more? Dont know what is in me.
I went thru the 1st half of the 10 km in around 20 min!
