Bike - Endurance vs Interval
I have just finished my first triathlon season. I have mainly done super sprint triathlons and am finishing towards the front of the swim and recording the fastest run splits but I am really being let down by my bike times.
What ratio should my bike training consist of in terms of endurance : interval training.
I am currently putting in 3 sessions per week with 1 endurance and 2 interval sessions.
Is this enough or should I be focusing more on endurance as I want to move up to sprint triathlons next season.
Tl;dr: What should I do more of, endurance work or interval training?
