After more than 10 years, Catch Fitness 20 Week Challenge took a break in 2019 to create a new 20 Week Challenge and develop resources and challenges specifically for youth and workplaces.   While we do have another 20 Week Challenge planned it’s not due to be rolled out until May 2020.  You can register your interest for it here.

What people say

A health & fitness challenge
like no other!

Over 3000 people have now competed in our fifteen 20 Week Challenges.

*stats are from entrant feedback which is compulsory and while not all entrants complete it, the vast majority do.

How it works

In a nutshell

Entrants can start from April 30th.  Last date for entrants to start is May 21st.

  1. Get ready. Decide on two specific health and fitness goals that you’d like to blitz over the 20 weeks.  Maybe you want to have more energy or less back pain,  run 5 km or a marathon, overcome an injury, learn to swim, quit smoking, sleep better, lose weight, put on weight, be more confident in your own skin and everything health and fitnessey in between, we’ve got you covered!
  2. Get set. Have some ‘official’ tests done to see where you’re at in your two goal areas.
  3. Go! Read a chapter a week from our Winner’s Guide and start training at home, at a gym, in the hills, with your mates, with your pets, whatever, where-ever, however.
  4. Check in. During the 20 weeks have two session/s with one or more ‘coaches’.  These include PTs, Podiatrists, Dietitians, Therapists and a bunch of others.  This will help keep you on track and moving forward.
  5. Get re-tested at the end and be stoked with your results.
  6. Win stuff.  We have cash prizes and award certificates for winners, finalists and finishers.  Scroll down for more details.

If your ears have pricked up and this is sounding like what you want (or should) do this winter, read on.

What costs you won’t have
No supplements, weird fitness gizmo’s, pre-packed meals or infomercial thingies and you don’t have to join a gym, hire or buy any home fitness equipment.

Sometimes some of those things can be helpful for some people but we don’t sell any of them and we don’t receive commission or kickbacks from any places that do.

Apart from saving you lots of dosh our very independent status also means our information can be ‘pure’,  unbiased and 100% about your success.


  • The prize money in 2018 consists of 10% of all entry fees which will be divided among all winners.
  • Winners are chosen by judges primarily on the basis of having the ‘biggest and/or best improvements’ which we need to point out is quite a different and way more complex judging process than simply choosing entrants who rock out the best end result, as awesome as rocking out the best end result is.  It’s a process that also recognizes improvements may be incrementally smaller in people of higher fitness levels.
