Just joined as Gold member and have created a custom training plan.
Have changed preferred settings to metric so total workout distances have change but in training details everything is still displayed in miles / yards.
I'm sorry I'm late to this post, been having email notification issues for, it seems, awhile. Anyways, once you update your settings to metric, you WILL have to recreate/reimport your training plan so that the workout details are in metric - otherwise only the total distances change.
Using a high-volume schedule for many months is not the best tactic. Build speed and skill several months out, and then transition to a high-volume IM plan.
This training plan has only 2 workouts per sport per week and peaks at 7.5 hours per week of training. Use this plan if you are time constrained or if you want to focus more on your family.
