If you’re stuck at work, or not near a tv this weekend, check this link out for a live feed for the LeMans 24 Hr Race. Other places have it too, but below is the world feed from EuroSport. Tends to be the best overall coverage IMHO.
If you’re stuck in a car all weekend and have Sirius or XM, they have it broadcast as well. Channel 94 on Sirius, 208 on XM
