Heeeey! I’m so glad you found us, and have found the podcast helpful so far 
.
I think you’re in the right place 
. And you have come at a good time. We have just improved the customisability of Training Plans! 
I think there is significant overlap between the specific fitness requirements of Mountain Biking and hockey. For mountain biking performance, you rely on three main energy systems; aerobic, anaerobic, and ATP-PC.
It sounds like you’ve recognised that your aerobic energy system needs work, and it’s great you’ve started to work on it. This will lay the foundation to improve your anaerobic and ATP- PC systems, which are required for those repeated sprints and the very quick bursts of power.
A TrainerRoad Training Plan will lead you through this, ensuring that the progression is optimal to you.
I suggest you sign up for TrainerRoad, make a customised Training Plan with Plan Builder v2, and see what you think.
Give it a whirl, and if you decide that it’s not what you’re looking for within 1 month of signing up, shoot us an email support@trainerroad.com and we’ll give you your money back.
