Attack Interval group ride question

Hi! I’m nearing the end of the SS18 week plan and have a question about the Attack Interval-Esque group rides. The only races I’ve ever done are zwift races and I’m usually just holding on for dear life, so I have zero experience at what qualifies as an attack. 90% of my riding is on zwift, and if I ride outside my “group” consists of either just me, or my husband and I. For these rides should I basically try for 5-6 full gas Strava QOM segment efforts outside? How long should these attacks be? 1 min? 5? 10?

Thanks so much for your help!

So a race like that on Zwift you are most likely riding most of it at or near your FTP. Very little variability like you would find from a real world race or hard group ride. Like you said it’s just hanging on so there is little on / off effect.

If you wanted to do an Attack style ride on Zwift the best way to do it is rolling around at low zone 2 but picking points of where to go full gas. These should be short burst that are 30 seconds to 4 minutes long. Each of the courses do have some type of little hill that you can attack up. Should be full gas all you have. Or if you are coming to a corner you can attack coming out of the corner for 20 - 30 seconds. Each time you come to a banner do a full out sprint.

When outside you can go for 5 - 6 Strava QOM, this would be great motivation. Try to keep them under 4 minutes in duration. With Attack style intervals you want to be riding at 120% + of your FTP so more of an anaerobic effort. Try to get in a total of 20 - 25 minutes of zone 5/6 time over the course of a 3 hour ride. Space them out over the course of your ride so you have some early, in the middle and late, much like a real group ride or race.

I think we need to do a podcast on group ride simulations ! Alternatives and workouts :nerd_face:


I’ve been subbing out mtb rides for these group rides and attacking the terrain. It’s been pretty spot on for if and tss

Exactly @m.vareschi - attacking the terrain , what I described in today’s podcast during the AmEX rides - all zones from bottom to top of the hills

Thanks for the replies!

I think I’ve done a pretty good job group riding for the rest of the plan. I was lucky to have a zwift group on Saturdays until the sun came out and Covid restrictions lifted. After that I sweet spotted up the climbs or I SS leapfrogged from group to group in zwift ride events and hit my necessary TSS.

The attack terminology was just a little too open ended for these last two, I really need to be told exactly what to do, haha. I’m glad I asked because I probably would have attacked the Volcano KOM which would have been closer to 8minutes and double the 4min limit set by Jake.
