This minor update includes a fix for Tour of Watopia XP bug and a pile of Training Plans added to the on-demand workouts list. Here are the details…

Tour of Watopia XP Bug

The Tour of Watopia just began last week, and it’s hugely popular since you get double XP for all your miles. But there was a bug which caused some Zwifters to not receive double XP! Here’s the bug as described by Zwift’s Shuji in a forum post:

We’ve identified a bug that impacts double XP in Tour of Watopia events. This bug occurs when a Zwifter warms up prior to joining their Tour of Watopia event, declining the initial “join event” prompt, and later joins the event without first ending their warm-up session.

This update fixes that bug (we haven’t tested to confirm). And before you ask, Zwift has stated that “We are unable to credit accounts with additional XP”, so if this bug affected you, it appears you’re outta luck.

Training Plans Available as On-Demand Workouts

February’s update added the three most popular Training Plans to the On-Demand Workouts list, making all the workouts in those Training Plans easily accessible at any time.

This week’s update added a pile of additional Training Plans to On-Demand. We’re seeing the following Training Plans now available as On-Demand Workouts:

Active Offseason (folder named 12wk Winter Plan (Advanced)
Back to Fitness
Build Me Up (added in February)
Crit Crusher (folder named 8wk Race Day Prep)

FTP Builder (folder named 6wk Beginner FTP Builder)
Gran Fondo (added in February)
Gravel Grinder
Pebble Pounder (added in February)

That leaves the following Training Plans not yet available as On-Demand Workouts:

Multisport Mixer
Zwift 101

A Note About Frame and Wheel Speeds

Many of you have been asking about revised frame and wheel speeds from the 1.23.0 March update, because we’ve mentioned that some items were modified, including the Chapter2 TOA whose performance after last month’s update made it the best all-arounder in game.

~~We’re still running tests on the fastest frames and wheels to get updated numbers. Until then, here’s how we would summarize what we’re seeing so far:~~

The TOA was slowed down on the flats, but so was its closest competition, the Scott Addict RC. On the climbs, the TOA stayed the same, while the Addict sped up a bit. So now the TOA has a slight advantage on the flats, but the Addict has a similar (~2 second) advantage on the climb.
So far almost every one of the fast frames and wheels we’ve tested has been slowed in our flat tests by 7-9 seconds, with the notable acception of the Canyon Aeroad 2021. The interesting effect of this is that the Tron bike was only slowed by 8 seconds total, while all other bike+wheel combos will be slowed by more like 10-15 seconds. End result: the Tron is a better choice than ever, although the fastest frames with a disc wheel still beat it on flats by about 8 seconds.
Whoever updated the aero settings for the fastest frames didn’t change the Zwift Aero frame, so it’s now matching speeds with the Cervelo S5 2020, Specialized Venge S-Works, Felt AR, and Uranium Nuclear. ¯\_(ツ)_/¯
The new gravel wheels, which promised nice performance boosts on Yumezi’s Temple KOM, have been slowed a bit, reducing their advantage. They’re still much faster than the stock Zwift gravel wheels, though.

Overall, it appears that Zwift made numerous adjustments to equipment performance, mostly on the aero side of things, which slowed many items down by 7-9 seconds over our ~50 minute flat test. We’ve reached out to Zwift asking for details on what changed, but so far they aren’t sharing that info. So we’re left with more testing to do.

Update 3/21/2022: after further testing and a lot of digging, it’s clear Zwift did not make a lot of changes to frame or wheel performance in this update. Our timing changes were due to a temporary (and as yet unspecified) issue in our systems which has since been rectified. Ride on, friends.
