Ah, time trialing. The race of truth. You against the clock. While they aren’t as popular as scratch races on Zwift, the individual time trial (iTT) format is something every rider should experience at least once. It’s a challenge of pacing, mental fortitude, of course, physical strength.

#1: Know Yourself
Self-knowledge is such an important part of racing, and the only way to get it is through experience.
The more you ride, the more you’ll learn what threshold work really feels like – and this is so important for time trials. Yes, you can use the numbers on screen and try to hold a particular wattage – but what if you are a little fatigued going into your ride? Or what if you’re actually stronger than your last FTP test indicated? This is where being able to “feel” your threshold is so important, as it lets you push to the max of what you can handle right now.
It’s also important to know how quickly you recover from over-threshold efforts. Are you the type of rider who really needs to hold a steady effort, or can you throw in regular over-threshold efforts then recover? This will determine how you attack different portions of a course, especially when it’s a hilly time trial.
#2: Know the Route
Experienced racers always recon a TT the course, because (as we’ll see below) this lets you plan your effort.
Outside rides present many variables as well: wind, weather, road surface, etc. Time trialing on Zwift simplifies things somewhat by removing many of these variables. Plus, all the Zwift route details you need are available within a few clicks. Check out our Complete Master List of All Zwift Course Routes for detailed maps and descriptions of any Zwift route.
#3: Don’t Skip the Warmup
When your race begins you’ll go from zero to threshold quickly, and this will be a shock to your system if you aren’t sufficiently warmed up beforehand. Take the time to perform a complete warmup, beginning with easy spinning then ramping up to threshold heart rate levels.
How much warmup do you need? This varies from rider to rider, but generally the shorter the race, the longer the warmup. A 20km TT may require a 30-minute warmup, while a 40km TT may require 15-20 minutes. (Shorter races are ridden at higher power levels, thus requiring more substantial warmups.)
You should be at the start line sweating and thoroughly warmed up. Ready? Let’s go!
#4: Start Slow
Don’t come out of the gate with guns blazing. Get up to speed in the first 30 seconds, but don’t fatigue yourself early. Riders commonly overcook themselves in the first few minutes of a time trial due to adrenaline, excitement, and fresh legs. Don’t fall into the trap!
Pop quiz: which is better?
- Riding at 100% of FTP for 10 minutes before blowing up and having to finish with 30 minutes at 80% of FTP
- Riding at 90% of FTP for the first 35 minutes, then 100% for the final 5 minutes
It’s an over-simplified example, but you get the idea. #2 will get you further, faster.
#5: Over-Pace Uphill, Recover Downhill
If your route is anything but pan-flat you will want to plan your power on the hills. To keep it simple, try to hold 5-10% over your “race pace” power when climbing, then let yourself drop a bit below race pace once you’re up to speed on the descents. This uses your power most efficiently, which in turn maximizes overall race speed.
It’s easy to cook yourself when the climb starts and the resistance increases, but don’t do it! Rather, start slightly over pace, then increase the level of over-pacing so you can finish strong and accelerate over the top. This is known as “progressive over-pacing.”
Bonus Tip: Upgrade Your TT Rig!
Time trialists are famous for obsessing over their bikes, constantly tweaking settings and upgrading parts to get the most aerodynamic yet ridable setup.
It’s easy (and more affordable) on Zwift, and upgrading from a basic TT setup can save you 90 seconds or more over an hour-long race. So pick the fastest bike you can afford! Read Fastest TT Bike Frames and Wheels at Each Zwift Level for guidance on picking the fastest frame and wheels.

I’d say your advice to push on hills and recover on flats is right, but the target climbing power is variable depending on the climb. Something like the Leg Snapper can probably take as high as 25% over threshold on a 10 mile TT whereas the Aqueduct on a full length or 20 mile Douce France TT calls for a more moderate approach.
Barcelona is it’s own special math problem.
Be aware that TTs are a specialist event where the big engines without necessarily a great top end can shine. I can beat many lighter weight whippets through experience and being able to hold a pace I know I can finish at, whereas they are better uphill and at repeated efforts. If you can’t place top end in a bunch race, give TTs a go, they’re a different animal!
“Negative split” flat TTs, especially when you feel fatigue might affect your theoretical FTP performance. On the return leg, start to evaluate how you feel and how much harder you could go for the final ~3Km/5mins. Ignore what other riders are doing around you, concentrate on your effort and how you feel, you might overtake those that set off before you or be passed like you were standing still by someone who started after you. From my experience, it’s rare that I’ve had a rider just ahead of me, going at a pace just a fraction higher than I might… Read more »
Come race Stampede with us! This last round has been alternating 16.1 km/32.2 km custom distances each week using the TT module on routes that don’t usually use it, but means that you can’t see the other riders so it’s true TT style. It’s been super fun! The next series will be some new twist, but it will always be an iTT. First race goes Sunday afternoon/evening and then times throughout Monday.

Thanks for the invite, but 1900 is a bit too late for me, my Direto makes a lot of noise at race pace despite being on two mats and sound insulation to our downstairs neighbours is awful… So I try to be noisy between approx 1000 and 1800! I thought about buying a Lifeline Turbo Rocker last weekend from Wiggle/ChainReaction for ~£160, to see if I could reduce the saddle discomfort that kicks in for me from ~50mins and to see if it would reduce vibration noise going through the mats and carpet to the wooden floorboards… But I dithered… Read more »
Tuesday’s at 7pm GMT (UTC)
Cleveland Wheelers also have a TT series going which has a new route each week.
Category based with 1 min gaps between categories so you don’t get lured into going too hard.

Thanks for the invite, but as I replied to Brent, it’s a bit too late for me. I no longer join the Singletrackworld race league on Tuesdays at 1930 because of noise and sleep issues.
TT’s are becoming my faves. I love the idea of racing against the clock and beating my previous time. I do agree with knowing your body’s limits though. I’ve seen many start out too fast, then lose power. Pacing is very much key in a TT. I also think varying your cadence helps to relieve leg fatigue. For instance, I will spend a few minutes at a lower cadence (65 rpm), then switch to a higher cadence (100 rpm) at the same power. I think this helps to utilize different muscle groups during the race. This technique works for me… Read more »
do TT helmets save time in Zwift?
I don’t think so but there is a zwift insider article about it
If only upgrading my mental strength was as easy as upgrading my Zwift TT rig 😂
Come join my Mountain Massif TT’s – brutal but fun. These climbing ones are a totally different ball game!
yeh nah
Road surface matters: gravel, dirt, bricks, cobbles, and wood planks all have different effects on speed. Just like hills, increase the power on slower surfaces. Out and Back Again is a good course to practice variable pacing strategies for both hills and road surface changes.
