Zwift Racing League Week 6 Guide: Empire Elevation (Scratch Race)

The sixth and final race of Zwift Racing League 2025/26 Round 2 happens Tuesday, December 9, and we’re back in NYC for a scratch race on the Empire Elevation course. This new route has some sneaky climbs, escalator intrigue, and a very spicy finish.

There’s much to discuss, including crucial course segments, powerups, bike decisions, and strategic options. Let’s dive in!

Looking at the Route

Empire Elevation is a 26km long point-to-point route with 266m of elevation gain from start to finish. This is a new, event-only route created just for ZRL, which means many riders haven’t yet completed it, although most will be familiar with the New York roads it covers. All categories will be racing the whole route:

Clearly, the finishing climb up the NY KOM is the big feature of this route. But there are a few slight warmup climbs before we get there:

  • Climb up from Peristyle Sprint @ 3.8km (900 meters at 2.4%): the first climb on the day, even if it’s a small one.
  • The Hill KOM @ 5.9km (500 meters at 3.7%): another short one, but a bit steeper than the first.
  • Manhattan Bridge @ 10.8km (1km at 2.6%): a draggy but draftable climb up to the mid-bridge Sprint banner.

Let’s Talk Escalators

Riders will take three downramps into subways during the course of the race… and also three escalators up and out of the subways. The downramps will certainly speed things up, but it’s the escalators that may make things truly interesting, if lighter riders choose to take advantage of what they offer.

You may recall, in preparing week 4’s race guide, I did some bot testing on the new NYC escalators. I ran bots of various weights up one of the longer escalators on the route (the final escalator you’ll hit, in fact). Each bot’s power was set so they would all have approximately the same escalator entry speed (~46 kph), and that power remained steady as they went up and over the top of the escalator. Here’s how much each bot slowed between entering and exiting the escalator:

  • 50kg bot @261W: slowed 3.2 kph
  • 75kg bot @339W: slowed 11 kph
  • 100kg bot @390W: slowed 16.1 kph

It appears as if Zwift is adding a flat power boost to all riders on the escalators. (In the comments section of the week 4 post, astute ZI readers Carl and Tom used some climbing speed calculators to estimate it at 1200-1400W.) If instead Zwift had given the same w/kg boost for all riders, the speed gap would be minimal. But 1200W is a huge number for a lightweight rider (20 W/kg for a 60kg rider) while being comparatively tame for a larger rider (12 W/kg for a 100kg rider), which is why the bot tests show what they show.

Zwift has acknowledged this is a problem, and they’ll roll out a fix soon. But it won’t be out before Tuesday’s race, as far as I know.

If I were a light rider, I might take advantage of this and attack on the escalators to soften the legs of heavier rivals. I could also just soft pedal up the escalator to conserve my energy! Think about it: assuming Zwift is indeed adding 1200W, a 60kg rider could coast up the escalator while a 100kg rider puts in a solid 8 W/kg dig, and both would have the same effective W/kg:

  • 60kg at 1200W=20 W/kg
  • 100kg at 800W+1200W=20 W/kg

Watch for escalators at 10km, 15.8km, and 21.7km.

NY KOM Finish @ 24km

The official KOM segment (shown above) is 1.4km, averaging 6.3%. But the actual climb is 1.8km long, averaging 6.2%. This will be a legit VO2 max effort: expect the full climb to take just under 4 minutes for top riders, almost 5 minutes for B category, and 5-6+ minutes for C category and below.

This is a fairly steep climb, so drafting will offer a minimal advantage, except on the three short flat bits. And the final 200 meters are the steepest part, so it’ll be a fiery finish for Round 2!

PowerUp Notes

Powerups will be awarded at each segment arch, including Power Segment arches in the subways, which means we’ll have 8 powerup opportunities on this route. You have an equal chance of getting a feather, van, or helmet powerup at each arch.

Lightweight (feather): reduces your weight by 10% for 30 seconds. Save one for the final climb, since it’s the most important section. You may also want to use them on the escalators if you’re a heavier rider.

Draft Boost (van): increases the draft effect you are experiencing for 40 seconds.
Use at higher speeds (flats and descents) when you are already drafting off another rider (since this powerup only helps when you are drafting.)

A simple white helmet with a visor, shown in profile with three lines behind it to indicate speed, centered on a turquoise circle with a gray and white border.

Aero Boost (helmet): makes you more aerodynamic (reduces your CdA by 25%) for 15 seconds.
Use at higher speeds (flats and descents), especially when no draft is available (although it is still useful when drafting.)

Bike Recommendations

This race’s steep finishing climb definitely makes me steer away from pure aero setups and look at climbing bikes and all-arounders instead. While a more aero setup would have a time advantage on a solo effort of the whole course, what you’re really looking for is maximum advantage on the finishing climb.

My recommendation, then, is to use the new ENVE SES 4.5 PRO wheels paired with one of these bikes:

Of course, your frame’s upgrade status should impact your decision. A fully upgraded Aethos will outclimb the other four frames, but that’s not the case when comparing un-upgraded versions.

More Route Recons

Lots of recon events are scheduled on upcoming ZRL routes, led by various teams. This is a new route on fresh roads, so many riders will find recons particularly helpful this week. See upcoming ZRL recons for this race at zwift.com/events/tag/zrlrecon.

Additionally, riders in the Zwift community do a great job every week creating recon videos that preview the courses and offer tips to help you perform your best on the day. Here are the recons I’ve found (comment if you find another!)

Strategic Options

How will the race unfold, and what strategies will riders employ to bring home a team win on Empire Elevation? Here’s what I predict:

  • Escalator pandemonium: Expect some lighter riders to attack on the escalators, as explained above. This becomes more likely as the race progresses.
  • Escalator and chill: Expect some lighter riders to simply coast on the escalators, as explained above.
  • Going long: Teams with pure-power riders who don’t fancy their chances in a W/kg slugfest may attack on the flats to get up the road and boost their chance at a high finishing position.
  • Save it for the climb: Most riders will do this. Simple conserve, conserve, conserve for the first 24km, then “give it the beans” for the final 4-6 minutes and hope for the best.

Was this written before the escalator fix was pushed out? I thought that was taken care of already

Hi Eric,
Thanks for escalator credits.

I checked 80kg 160kg and 320kg.
Doubling to 160kg brought the speed from 25kmh to 13kmh, still consistent with a flat 1250-1300w. Hard to nail down with bike weight and aero drag at that point.

320kg however went up at 11kmh instead of an expected 6-7kmh.
Could be for any hard-coded min/max values at that point, like a hidden hard-cap of 200kg on weight in calculations with slopes (to prevent people from going down at 300kmh on the Alpe, maybe). It did feel incredibly slow to accelerate on the flat. I might try dropping from the Alpe or Radio Tower with different weight to see if there’s a hidden max weight in slopes.

@Eric Schlange I can confirm there is a hard cap under or at 200kg for all calculations CRR/slope/aero. I descended Cheddar Gorge 125% in 4m48s with max speed exactly 90.3kmh with both a 200kg and 300kg avatar coasting on Cadex. My avatar came to a stop super far near some pens, 10 meters close test to test. For comparison at my real weight it’s 5m36s 79.2kmh.
So that explains the 11kmh up the ramp at 320kg versus predicted 6-7kmh.

Hi Eric! Thanks for this great summary for tuesday – just wanted to double check – your notes say you’ll get power-ups in the subways – does that mean all 3 of the power arches in the tunnels?

Lead the BEAT prep ride this morning and I didn’t notice any banners / sprint screens during the subway parts so probably there are none in the race too.

Nope I don’t get them in our official ZRL prepride and I used my PU before going down into the metro situation.

So Zwift AGAIN benefits lighter riders….their w/kg-Approach is already way in the benefit of lighter riders (see flat races)…

No way. As a lighter rider I feel like I am at big disadvantage in most races to the big boys cranking out major watts.

How do you figure? Escalator insanity aside, this course has it’s finish at the top of a 1.4km 6.3% average climb.

Hills are a part of cycling.

This is the first “real” hilltop finish in ZRL this year.

I think the course selection has been fairly balanced so far, actually. At least when it comes to variety of terrain.

Honestly nothing so far has benefitted true “climbers” who will be at their strongest for long sustained climbs over 10 minutes.

Lots of stuff for punchy guys in season 2 and there was a lot of pure watts stuff in season 1.

I’m a certified climby boi competing in the As and WTRL never selects courses that are made me for me. Yet I still get stuck in and ride my hardest. Quit your bitching and get stronger.

Well, that was unnecessary. I’m only pointing out that this course clearly suits climbers. Where do you read “bitching” into that?

As a middle-weight rider, around 70kg, I can say that Zwift has made algorithms that do not benefit me. Due to my weight, I am constantly in a disadvantageous position. Both on climbs and on descents.😭

As a heavy Zwifter (down to 300lbs/137kg this year), I have actively avoided races/rides in NYC after completing them in the Zwift unlocked events, because I just get DESTROYED/gapped on the escalators despite dumping over 1000w for the effort up. This validates my experience and makes me very excited to see how Zwift updates to even things out a bit. I’ll be watching for the update and will have to give the NYC map another chance once it goes live.

As a 100kg rider I am getting a hand full these weeks hea? First they change the draft, so the one thing we do good, is less good. Then we get screwed over at the escalators, while also having this finish. I know what my new years resolutions will be!

Climbers don’t like this course.
Sprinters/Big guys don’t like this course.
Middle weights don’t like this course.
Eric doesn’t like this course.

Could we NOT have this course (or any course including this KOM) on the WRTL schedule again?
