TRI247 Workout Series #198 – ‘Micro Burst Intervals 2 – The Sequel’

Wednesday, 17th November 2021 – 7.05pm UK time on Zwift

(ZWIFT LINK >>> https://www.zwift.com/uk/events/view/2417558)

Join us tonight on Zwift for the latest edition of the Tri247 Workout Series. Free to join and open to ALL abilities, enjoy an hour of structured training with the added motivation of a virtual group training environment.

If you are new to Zwift and are not sure how it all works, it’s well worth checking out these recent articles we’ve published to find out more:

This is the follow-up to last weeks Micro Burst Intervals session – imaginatively titled, Micro Burst Intervals 2 (!)

The Micro Burst Intervals 2 session

If you’ve ridden the original Micro Burst Intervals session, this one is an adaptation and development of that.

This time we are going to do three blocks of short intervals (5*20secs, 6*15secs, 7*10secs) at significantly above FTP level – and then repeat that. As the interval length decreases, the power targets increase and the rest intervals will also be reduced. It does feel a bit tougher the second time through…

If you are looking for a workout to complement your longer intervals  / base / sweetspot / threshold work, then this one will provide something a little different. The intervals are structured as:

  • 5*20secs @ 150% FTP
  • 6*15secs @ 175% FTP
  • 7*20secs @ 200% FTP

In order to ensure you and your legs are ready for the main set, the warm-up will be relatively long, progressive and include a few short and sharp efforts to get the legs firing and ready to go.

Join us at 7:05 p.m. on Wednesday 17th November 2021 (UK time) on the virtual roads of Watopia. Set your reminder now on the link below or via the Zwift Companion app.

[TIP – It is always worth having the (free) Zwift Companion app to hand on your mobile device. Within the workout screen you can toggle your FTP by +/- 10% ‘on the fly’, which will immediately change your power targets during the session. Legs feeling heavy, can’t quite hold your power targets? It happens! Rather than can the session, how about moving your targets down 5% first, before giving up completely? Alas, the body isn’t a machine and can’t always deliver as you hope/think it should, so a bit of flexibility and not getting too obsessed with the numbers can be a good thing!

On the flipside, perhaps you are having a good day or increasing the overall training stress of the session better meets your own training goals for that day? In that case, you have the option of nudging your baseline up in the same way.]

The session is genuinely open to everyone of ALL abilities. Group workout mode works fantastically in Zwift and ensures that the power targets are tailored to YOUR level. It makes no difference if your FTP is 400 watts or 100 watts, the targets you see will be specific to you – all while being part of the on-screen group.

Ride Leader – Debbie Coyle

Debbie is a successful Age-Group triathlete, who has recently opened an exciting new club, Comrades Triathlon Club, based in Essex. She’s also been a regular participant in the Wednesday sessions for the last couple of years, and we are very happy to welcome Debbie back as this week’s guest ride leader and coach.

Free (Virtual) Kit!

Every rider who completes a TRI247 ride (including our weekly Manic Monday Time Trial), will now unlock the bespoke TRI247 kit to their Zwift garage, to wear online whenever they choose!

Joining Instructions:

The workout will begin promptly at 7.05pm UK time, Wednesday 17th November 2021. It is worth logging in 5 or 10 minutes before the session to make sure you are set up and ready to go, where you will be able to warm up in the virtual ‘holding pen’.

Look for the TRI247 Workout Series event in the list on the right of the screen once you have paired your sensors. Click to JOIN and you will be taken to the start line ready to begin the workout.

Make sure you have set your FTP level correctly before you join the workout as all the intervals are based on a percentage of FTP so it is important to get that right. If in doubt, dial the FTP number down 10 or 20 watts as it is better to finish the session than to feel like it is too challenging.

If you have never used Zwift before but don’t want to miss out, head to the Zwift support page for tips on how to get the most out of your setup.

After the session head over to the TRI247 Facebook page for some post ride chat.

Zwift Group Rides: TRI247 Workout Series

The cool thing about a group workout on Zwift is that varying levels of ability can ride together in a group and all finish the session together having done the same relative effort, even if the actual watts are significantly different. It is not a race, but a shared goal to get a good session in the training log.
