Decent time for 10km

[jsmoke]

Not a huge distance I know and flat conditions, no hills at all including downhill.

I am looking at previous times for a beginners duathlon and they are hitting around 21mins which seems fast for so-called beginners.

I just did 5.7km in 20mins at around 60% effort but had hills.

Exactly seems fast to me especially if you have to run after it.
