my entry:

Achieved this effect like this
Copied layer
made a layer mask on the copied layer, select the mask and then select the Gradient tool, set it to radial, then Frograound to background. With that draw a line about the lenght of the bike then carry forward lsightly to allow for the image blending. Check the result by clicking the eye icon on the background layer, this hides that layer, letting you see the top layer.
Click on the background layer, then select Filter>blur>radial then click Zoom in the options there, then select where and how much blur, i centered it over the cyclist(afte 3 tries) and used a medium amount of zoom blur.
And thats it
quiet simple, but very effective
