Muzza...if you're talking power of 10, then a 1:20:00 on the dot would get you in the rankings...
IF...
it was a UKA event, and If this was your gun time rather than chip time.
The half I did bungled the results, and even though i passed the finishing line on 1:19:50 it came out as 1:20:00, just getting me into the rankings. The chip time was an even bigger screw up!!
Slightly oddly, my fastest time on power of 10 for half marathons is actually 23 seconds slower than my pb.
But that's the difference between starting very close to the line, or starting 30seconds back as they don't care about chip time.
ps Pub Phil... certainly do need to up my game...2 half marathons, 1 10miler, 1 10k and 1 5miler in next 4months hopefully will start the route!
