Average power on short intervals

I just did Taylor -2 and Ebbetts last week. I use a Wattbike Atom and I have found it hard to hit the average power of the short intervals. I was meant to hit 247 watts per interval today and hit about 230. I decided to put the target up 5% and I tended to hit around 240 watts after that.

Was this the best thing to do. The Atom is set to 3 seconds average power. It will obviously take a bit of time for ERG mode to kick in and ramp up so should you hit that average power on such a short interval?

Which version of powermatch are you using? For shortish intervals I turn the automatic powermatch off and use a fixed gap between trainer and Power output. The troughs tend to be garbage but the peaks tend to be spot on by half way through. I find it minimises the overshoot. If the intervals are really short I don’t even try Erg mode and switch to slope.

Do you start trying to hit the power a few secs before the intervals starts? If you start right as the timer reaches “zero” you’re not gonna hit the right average (even if the load in practice might be about the same). Just a suggestion

ERG isn’t the best for short intervals as it’s slow to respond and it effects all trainers and bikes, just some are better than others.
The graph looks pretty good to be fair and I expect the time in zone is pretty close to what is required.


I need to look at Power Match. I didn’t think I would need it for the Atom. I am not sure if it is on or off to be honest…

The Atom only supports ERG mode. Atom ERG mode only

If you’re stick with an erg only situation then as stated above you have to kick into the interval at 1 or 2 secs ahead, this takes a bit of practice as each trainer responds differently, also said before.
