I am not a professional. I am an intermediate cyclist that knows no end to the distances I'm capable of. I air to caution when I reach extreme speeds with thinking if I had to stop, could I.
There is no quit in me and though I started with a sprained ankle. I know the limitations of my body and stay within them. I stay hydrated and rest when my body tells me to. I try to avoid mid-day cycling since I tan easily and avoid heat exhaustion. I encourage safe traveling and utilizing your hand signals.
