This Weeks Goals

No specific goals this week, just continue with race prep and trying to match terrain of your goal race

Week 18


Bike 1h 20m Comments: Great transition practice today! Can be done with a bike trainer or on the street. Do a complete transition each time. Setup your bike trainer and complete race transition setup in a garage. 8 reps gives lots of time to work out your transition kinks.
Run 1h 00m 8 x (R 4:00, B: 10:00, R 4:00 )
Be careful of run intensities - at only 4 minutes each it seems easy to do them fast, but 8 reps is a lot. Keep all efforts at RPE 3-4. Up the effort the last 2 if you've got anything left...


Bike 30m RPE 4-5
Run 2h 00m RPE 3 using race nutrition/hydration plan.
Comments: Brick - Short bike and long run. Use race uniform if possible. The high intensity bike spinning will twist up your stomach a bit and provide a good test for nutrition and hydration in the run.
