Stages Cycling makes power meters for all types of riders. Power meters are a tool that help cyclists get the most from their training. You may be surprised, but many of the riders you follow through Pinkbike’s race coverage use Stages Power to maximize their performance. In Whistler, Stages Cycing collected rider power meter data and used it to quantify how much mechanical work the athletes did over the course of the EWS event. Kilojoules (Kj) are a direct derivation from power data of how much work was done by each rider, thus how 'big' the day was. For reference, a 1hr ride at moderate intensity for a normal rider is around 150kj and a Tour de France rider may expend around 3000kj.
For more, read here.
At the EWS in Whistler, Richie Rude (Yeti-Fox), Chris Johnson (The Nomads), Rene Wildhaber (Trek Factory Racing), Brook MacDonald (GT Factory Racing), Nate Hills (Yeti-Privateer) and Geoff Kabush (Scott-3Rox) all recorded outputs. Match the rider with their correct kj expenditure for a chance to win a Stages Power meter of your own. Only Registered Pinkbike users are eligible for entry; one winner will be selected at random from the correct entries.
**Stages Cycling will give away one Stages Power meter, valued up to $649.99 USD. (

Huh? I have a power meter on two bikes and my "moderate intensity" 1hr rides are usually right around 1,000kj.
150kj is 150,000j (energy)
1 watt is 1 joule per second (power)
1 hour is 3600 seconds
150,000 divided by 3600 = 41.6W (which seems very low)
1000kj = 1 million joules = 277W = which is pretty impressive (about 1 hour for a 25 mile road ride type power)
For an all day EWS by pros, I'd be expecting to see some big numbers up there....
Hope there's not a silly mistake in there!
Let's say an hour at 250W vs. the average peaky power trace on a 3 minute timed stage (even with brief stints in the 1000W range)
In other words, total, unequivocal guessing going on here.
1000 of those joules = 1 kilojoule (KJ)
kilojoules = watts X seconds / 1000
