How do you feel after track days

BGTV8

Most people fail to stay hydrated when spending more than 15 or 20 minutes on the track.

I have run in 1-hour race events in the past and unless you have something to hydrate you in the car, after 30 minutes or so (in a triple-layer race suit), your performance starts to fall.

Since I am officially now an old-fart, I actually have a cool-suit as well, for anything longer than a 20-minute race.

Last weekend I ran the Z34 as part of a team in a 6-hour relay where each driver gets 30-minute sessions over the 6-hours and that meant I was tired by the end of the day (I did 3 sessions in total). I drank about 2.5 litres of plain water and a litre of hydrating agent (supplement with requisite salts and minerals) during the day and "just about" kept up with fluid loss.

"Most" of the time, the feeling your experience is a consequence of mental fatigue with dehydration as the root cause. If you do not have a race seat, then you will also experience muscle fatigue as you use upper-body, back, abdo and leg muscles to hold yourself in the seat. A good seat and 5 or 6 point harness makes most of that fatigue go away.
