Rest between Base, Build and Specialty

I apologize if this has been covered somewhere else but in my 2 years with TR I am starting to doubt myself. As a 47 yo male using triathlon plans, should I be resting some between the Base, Build and Specialty plans or just moving from the end of Base to Build (ends Saturday - starts Tuesday) with no additional rest and then again from Build to Specialty with no additional rest? Thanks.

The last week of Base and Build plans is a downturn in volume so you should be able to roll straight into the next phase

However, if you’re feeling particularly burned out adding in an extra recovery week, or shifting from a 3/1 work/rest week cycle you could switch to 2/1 and see if that helps you out
