Sport Specific Doldrums

This week I backed off cycling training. No matter what I did, I was very low energy and just could not summon enough juice to work out at wattages and intensities in previous weeks.
What a frustrating thing. I am now building to my next race in June and feel that backing off now interrupts my progress. But I am trying to rationalize better and listen to my body.
A intuitive training regimen is prescribed by my coach. There will be lulls in my energy naturally and forcing my way through them without rest is only going to increase frustration and potential injury.
Some training programs have them built in every 4 weeks. Those coaches reduce volume by up to 50% on lower intensity weeks. My coach prefers to program them in based on how the body feels, as they do not occur as regularly as training programs schedule volume breaks.
They can also be sport specific. My swimming and running apparently have not been affected, while my cycling has clearly had a down-energy turn. Time to do a series of easy bikes for this week and then see how I do next week.
