Stuart Fraser in The Times reports that Kyle retired feeling unwell because of the extreme heat, and not because of injury.
A bit late to the party on this one as I've been away working but this is good news. Kyle has suffered before in the heat so if that is all it is ......
All the drivers were complaining about the heat and humidity.
my experience from spending a lot of time down in the middle east in UAE and Qatar between 2011 and 2014 is that we often have this perspective that it must be dry heat as it is a desert area. But it is not. The heat is brutal and at times the humidity can be brutal as well. Outside of November to February , it is not pleasant to be in and I am amazed any sport is played outside those months.
