I have been doing low volume plans and adding 2-3 75 minute Z2 rides on the “off” days. I this enough volume to make a difference? I don’t want to be on the trainer for longer.

Makes sense! That was my perception too. I guess I just got bit thrown off by the posters who said you don’t get any benefit under X minutes of z2.

Clearly this is not a popular take with the SS crowd, but everything I’ve read says you’re right. 75 mins are by no means junk miles, but it’s not enough for the LSD benefits the OP is looking for.

The OP said he’s doing LV plans plus 2-3 days of Z2. That is a solid approach to using TR correctly - LV intensity sessions + endurance riding. I think that’s about as good as you can get on about 6 hours per week. Once the weather warms up, he’ll be even better if he can do some 3+ hour endurance …

Every little bit helps. Don’t believe anyone who claims otherwise.

Wasn’t he talking about riding at LT1 and not in the zone below it though.

Is this a game of guess the animal on the treadmill? Was it a badger?

@Yukonranger If prior to doing 75min Z2 rides on endurance days, you were doing 60min Z2 rides (for example), then yes, that is enough to improve. If prior to doing 75min Z2 rides you were doing 90min Z2 rides, then you’re likely just doing enough time to maintain. Once you have adapted to doing t…

The question will be whether a 75 min Z2 ride is challenging for you. For Z2 is normally the duration that challenges the muscles. Z2 for one hour might be easy, easy for two hours, easy for three hours, moderate after four hours, hard after five hours. You’ll want to progress the duration which …
