- There are 8 training sessions per week with an average training volume of 6 to 10 hours per week.

🏋️♀️ Strength and Conditioning sessions to help you avoid injuries from a NASM Certified Personal Trainer
🧘♀️ Stretching and Meditation to ensure you are ready to race
Training Notes:
🏊 Pool Swimming will be structured and include detailed swim drills & intervals.
As we get closer to race day there will be open water swim specific sessions to practice your sighting skills as well as your ability to swim continuously.
🚴♂️ Cycling
Depending on accessibility to trails, the assumption is that you will predominantly ride on the road.
When you have the opportunity to ride on trail, do so.
- the more you ride on the actual course or one similar the better.
- speed: incorporate 2-4 lots of 5min efforts in the middle of the ride.
- hills: go hard on every hill ascent and practice descending too, especially on the trails.
- weekend cycle: is at a slower pace, this is your endurance ride.
🏃 Running
Trail is best due to its technical aspect.
- hills: option is either an undulating course or hill repeats with easy running pre and post.
- intervals: these will be internal or fartlek runs.
- Saturday run is directly after the cycle to get the legs accustomed to running off the bike. (Brick)
- Sunday run: is at a slow pace, this is your endurance run.
