SISU Racing took the months of November and December to pilot two separate race series concepts. After working out the niggles and fine-tuning the schedule, they’ve just announced the SISU iTT and SISU Climb race series, beginning in January!
SISU iTT
You, your TT bike, and a race against the clock! Fresh routes every week, available in eight time zones (midweek thru weekend)

Each week is a stand-alone race. There is also a monthly GC classification on ZwiftPower for racers who complete all races (see January GC).

Do the iTT events use a staggered or mass start?
the article states the following…
TT bikes – all riders will be visible on the course without a draft.
The price of freedom is eternal vigilance
The pilot events for the TT were staggered starts. It was a good series and enjoyed having series rankings, it made me keep going back for more.
Sorry to be picky, but the phasing of ‘Riders on ZPower or without heart rate data will be removed from the results’ could easily be understood that if you’re on ZPower you will be removed from the results’. Maybe ‘Riders need to be signed up to ZPower and need heart rate data to be included in final results’ is a little clearer. I know a lot of people know what is meant, but there are a lot of new faces on here as well.
ZPower isn’t Zwift Power.
Zpower is an estimated power, for those that have dumb trainers and/or no power meter. Must have an actual power source or else you’ll be removed.
But you’re also right, you need to be registered on Zwift Power (the site) as well, if you want to be ranked
Hi,I rode the TT but the lack of information on the corse during the ride was disappointing
FWIW, the ITT race for Feb 1-5 has been changed to Chasing the Sun.
