Much like everyone else on this forum I seem to be constantly readjusting plan to events and have just had my last race option for the year cancelled.
So have decided to plan for next season. I am planning to hit up IM Marbella 70.3 in April next year and then follow up with a full IM in around August/July (possibly Tallinn, Estonia - looks interesting and heard very positive reviews).
Making this plan using a combination of plan builder, standalone plans and my own additions I have been trying to get a better understanding of what is meant by a “base”: what are we trying to achieve? and how do we measure it?
What happens physiologically during base training (using either traditional or sweet spot)?
How do I measure my “Base”?
Reading online, I see people writing about Efficiency indexes (HR vs Power). I don’t think the usefulness of this metric only applies to Base and wouldn’t know how to use it to see my base developing.
I’ve also seen people suggest that your resting Heart rate is a good measure along with your VO2 max (kg/l/hr).
Would be great to get some insight into this plus does anyone know of any Chad deep dives into this topic. I really need to demystify this concept!
