It's just four weeks until March 19 (we know, we know - where is the year going?), and that gives you exactly four weeks to train for the second NTC Tour Sydney - a five-hour, high-octane workout with you and 2500 other women at Darling Island Wharf, Pyrmont (side note: it's a great place to play 'spot the fitspo star').

A group workout like no other, NTC Tour mixes up highlights of the Nike+ Training Club workouts with spin, bootcamp-style drills, boxing and running. And to make sure you're fighting fit for the day, Nike offers a training program in the lead-up. There are two HIIT seshes remaining, on Saturday Feb 27 and Saturday March 5, to boost your own exercise regimen.

If the chance to be trained by Nike Trainers isn't enough to grab you, this might - all the NTC Training Journey Saturday sessions take place aboard the MV Epicure. Yep - they're on a boat. Departing at 9am from Man O' War wharf (just by the Opera House), the two-hour sessions get you sweating to a stunning backdrop of 360-degree harbour views - not a bad upgrade from your morning run.

To register for the training sessions, visit and to sign up for NTC Tour Sydney on March 19, head to Feeling hesitant because it sounds too hard-core? You know what they say - just do it.
