I'm not familiar with Roger's PVR offering, but the Bell (Dish) PVR allows you to access a PVR recording that is still underway and either 'View' (shows the recording from the point it's at right now) or 'Start from Beginning'. You can watch the event and pause/rewind/fast forward as with any live show, without affecting the recording in progress.
Provided your PVR will do that, you already have most of the solution. Hook up a cheap Slingbox to it (if SD is acceptible quality), make sure both it and the laptop are on your local network, and you're all set. Just use the Sling client application on your laptop to access your Slingbox over the network, and you can watch the race via remote PVR just as you would on your TV.
It will work with your laptop connected to your network either wired or wireless - you're not going to see any bandwidth issues, especially at SD resolution. You don't need a Slingplayer/Slingcatcher or any other hardware than a simple Slingbox. If you're wireless, you've essentially created a portable TV with PVR you can use anywhere in your house or yard.
Edit: I just checked out the current Slingbox offerings and the Slingbox SOLO would do what you want, and stream an HD image as well, for about 200.00 CDN.
