Hi,
I was out training on Saturday and, ever since, don't seem to have the
"umph" to do anything non-trivial on my bike. The thing is, physically,
I don't feel particularly spent... As such, does anyone have any
experience or knowledge on "mental fatigue" -- does it really exist, or
is it just an excuse for laziness?! If it is a problem, what can one do
to get back in the groove?
Let me give further details; in case they are of any use... My route on
Saturday was only 45 miles; however, it contained two hard climbs (750
feet, at about a 15% gradient) and one moderate climb (same elevation,
but about 6%). The total ascent was something like 3,000 feet; I felt
like a bit of a sprint near the end, too. It took me about 2:20,
keeping my heart rate in zones 3 and 4 (average 3.5), burning a total
of 3,000 calories (after having consumed about 350kcal of breakfast).
It was a very blustery day and I had to battle the wind all the way --
which, as I'm sure you'll all empathise with, is very frustrating! The
traffic didn't help either.
After the ride, I was neither wobbly, nor did my legs feel like
concrete! At most, about a quarter of that spent energy was replaced
(I'm trying to lose body fat, as well as train); however, I have eaten
sensibly since and have accounted for my resting metabolism... I didn't
get the greatest night's sleep on Saturday (the irking of the wind had
rather broiled me up!); but I slept reasonably last night and felt
quite perky this morning.
On Sunday evening, I tried to do some interval training: I managed just
6 minutes before giving-up! Like I say, I wasn't physically incapable;
I just didn't have the get-up-and-go to do it, or persist... This
morning, cycling to work wasn't a problem (it's only 1.5 miles -- my
grandma could manage that); but at lunch, I always like to go for a
good ride. Same problem: physically, I could have managed (about 10
miles; including an 800 foot climb at about 12%); but I just couldn't
be bothered to put the energy in!
I don't particularly feel as though I have overdone it, in the sense
that my body doesn't feel spent or over-exerted. I haven't felt hungry
or faint, so presumably the energy expenditure wasn't the problem,
either... The only thing I can thus think of is the concentration put
in to get up those hills, keep my heart pumping hard enough, overcome
the wind and avoid the traffic has, psychologically speaking, tired me
out.
Any thoughts? I don't want to have to take too long a break before
continuing training; now, or if/when it happens again.
Many thanks 🙂
