I disagree. staying in the tour would be bad for his mental health after what happened today.I really don't know what to say...
-Unless there is a medical reason for packing it in, riding out the TdF might be good for his legs/form.
-Obviously if there is an issue, stopping ins wise.
Anyway, keep fighting, see you soon RE!
And not sure how it can help him physically when it seems his batteries are empty.
