My recent 35:20 time for 10k implies that I can run a 16:57 for 5-kilometers.
So last night I attempted to break 17 minutes in the monthly time trial on the track at Oda Field. Six years ago I ran around 16:50 in a 5k time trial, but in recent years I have been content to go out relatively easy on the first kilometer and try to run progressively faster on each kilometer.
Last night I did the first kilometer in 3:23 and tried to maintain that pace.
It was painful - as you can see in this picture.
I faded over the
3rd and 4th kilometer, but am reasonably pleased with the 17:05 I did manage to run.
