This may have been answered previously but I couldn’t find it.
I am just finishing sweet spot base low volume. I am an amateur and this is only my second off season doing interval training. I found adding a Sunday ride to the sweet spot base plan was sustainable and usually added a 1:30 to 1:45 min low intensity Sunday ride. Partly because I have the time and partly to increase TSS. For the low volume general Build Phase upcoming I will be doing significantly less TSS if I don’t add a Sunday ride. My question is what to add. Sweet spot, threshold or continue adding zone 2 work. Any thoughts? I have no specific goals. I do some gravel racing in spring, a few 2hr mountain bike races in summer and race cross in fall… all just for fun and only mildly competitively.
Any help is appreciated. Thanks!
