That's not good. I sometimes wonder whether their massively excessive caffeine drug use is contributing to the rate of problems in this area.
Update news of Colbrelli ; it seems he is alright,
but more tests are needed to determine what caused the unstable cardiac arrhythmia that required immediate defibrillation.
Online there is a lot of speculation what caused this, I did not read anything about a caffeine drug ( caffeine is bad for the heart, imo ),
but for example Colbrelli tested a few times positive for Covid this season, some speculate this has something to do with it.
Also there are speculations that he overtrained himself to return in topform after he was ill, combined with the uphill finish yesterday.
For example, at the last moment the decision was made not to ride "his" MSR ; he was not healthy enough despite intensive training for MSR.
Better than speculation = the medical tests tomorrow in the Hospital Universitari de Girona.
A fact is that Colbrelli was lucky that Saenz de Cos ( emergency nurse ) gave him the
prompt+right+needed medical assistence.
