There are 3 types of railroad crossings; DANGEROUS, VERY DANGEROUS and EXTREMELY DANGEROUS.
I still see and hear about bicycle crashes when crossing railroad tracks .... a closer look ....
Years ago, when I was an aspiring amateur bicycle racer, I attended several one week pro bicycle training camps sponsored by several European pro bicycle teams. All aspects of professional bicycle racing were covered. One of the topics was that of preseason “base building” and its purpose that I had not heard of up until that time.
"THE MAIN OBJECTIVE OF THE BASE BUILDING PHASE IS TO DEVELOP THE CARDIOVASCULAR SYSTEM BY DILATION AND ADDING CAPILLARY DENSITY.”
