Gallery: Ellen van Dijk’s world hour record Trek Speed Concept

Van Dijk's track-adapted Trek Speed Concept will be put to the ultimate test of endurance Monday.

Ellen van Dijk is headed toward her hour of power on the Grenchen velodrome in Switzerland.

Van Dijk and her Trek-Segafredo team unveiled the Trek Speed Concept that the 35-year-old would ride in her effort to topple the world hour record Monday.

Per UCI regulation, all official world hour attempts have to be conducted on a regulation track frame. Van Dijk and Trek opted to modify the road time trial frame that won the Dutchwoman the 2021 world title rather than gambling on a track-ready rig.

The outcome?

An ultra-aero adapted frame looks likely to go fast.

“Today we had a little exam. We put it all together and we checked the CdA, and it was even better than before,” Trek-Segafredo head of performance said in a recent team release. “If everything is right, we think we can put the record over 49 kilometers.”

Van Dijk will be looking to go better than the 48.405km set by Joss Lowden in the same Swiss velodrome last fall.

“This has been a dream of mine for a very long time. The hour record is something that I have always said I wanted to do one day and now that day is finally here,” van Dijk said when she confirmed her effort earlier this spring.

“I get butterflies in my stomach when I think about doing it, a mix of excitement and nerves which is normal. You are always just on the edge with big challenges, and this is a huge challenge, so it is going to be exciting and frightening at the same time.”

You can tune in on the Trek team website at 5 p.m. CEST/11 a.m. ET to watch Van Dijk’s effort.
