I saw a report on Velo News that Chris Froome is once again battling a parasite called Bilharzin. It's been an on-again/off-again thing for him over the past few years. Call me cynical, but I think it's all a sham to give him an excuse to stay in second place! He can gain loads of time on Wiggins and be in yellow...but this "sickness" gives him the perfect excuse to hang back. Whatever.
