Cyclingpeaks is offering a live view of SRM data during each stage and posting the entire file afterwards. That’s cool and also depressing to see such low heart rates! That’s my heart rate during a casual riding to meet the team!
Polar is also transmitting data during the stage, OLN alternates between the two, but I haven’t seen Polar files live. They do have a S725X Tour Edition and a new partnership with Adidas.
The Live Update Window from Velonews offers, standings, jerseys, a google map and is perfect for following le Tour at work.
