Some people barely break a sweat running the City2Surf.
Some have a rest afterwards.
And some, of course, don't finish at all.
Skye Mitchell Innes did a test shoot straight after her first crack at the world's biggest fun run last Sunday (which she completed in just under two hours, together with a posse of school mates, both running and walking the course).
Scouted near her exclusive Sydney high school four months ago and almost immediately signed to Sydney's eMg Models, the sporty fourteen year-old, who also plays soccer and netball, has an upcoming 'new faces' editorial in Kneon magazine, shot by Christian Blanchard.
Mitchell Innes is 5'9" and growing - both her parents are over 6', reports eMg - and it's no surprise she caught the attention of eMg scout Simone Hellicar.
There is something quite androgynous about her face. Her striking mane of hair notwithstanding, in some shots she almost looks like a boy.
This is the same Sydney model agency that signed/developed 13 year-old Tallulah Morton in 2005.
As many would recall, Morton made her runway debut that year at Australian Fashion Week, opening Josh Goot's debut AFW show. With a 16 year age minimum now imposed on the event, however, that would obviously not be possible today.
That does not mean young hopefuls don't continue to enter competitions such as the Girlfriend and Dolly model searches - or that scouts aren't constantly on the lookout for new stars to develop.
With new faces such as Brigitte Mitchell, recently profiled by Frockwriter, eMg Models clearly has its finger on the pulse.
Here is a so-far-unseen test shoot of Mitchell Innes. Photos supplied exclusively to Frockwriter by eMg Models.
