NUCLEAR FIT DOUBLES COMPETITION
Your 2 person doubles can consist of 2 male competitors, 2 female competitors or 1 male and 1 female competitor. Both people complete the 1km run and then progress to the sequential functional fitness station where a combined individual effort is required. There are 6 different stations to complete along with 6 x 1km runs.
DOUBLES RULES
You must run and complete each 1km lap together, you must pass the start and finish line together. Your race time will be the last chip from the doubles over the line, The doubles must enter and leave the workout station together, however at the workout stations the doubles split the workout as they see fit. The doubles decide how many reps and how far in distance each competitor completes, it’s up to you. The weights, distances and reps format is listed below.
Here is an example: Urn Hug 30kg
Person 1 starts the carry whilst person 2 walks behind without obstructing any other competitors. The double can swap out at any time. Person 1 will pass the Urn anywhere on the course and person 2 continues the carry. At no time will two people be carrying the urn. Now person 1 walks behind person 2 and this process is repeated until the distance is covered and you both cross the finish line. You now must run 1km together. Both competitors must share the workload, but not necessarily equally.
