Day 2 /
10th January 2021
I wore my Fitbit again
last night to monitor my sleep. Here is the resulting chart:

Compared to the previous night,
I didn't wake feeling as
refreshed; it seemed like I work
at the wrong point in the sleep
cycle. I therefore marked the
chart with a yellow box.
I
woke at a few distinct points in
the night and recalled and wrote
down dreams, along with the
time. These again followed periods of REM
sleep according to the chart.
The third time I was actually
woken by my cat wanting to go
out, and fortunately he seemed
to do this at just the right
moment in my sleep cycle. I
apparently achieved over 8 hours sleep
for which the Fitbit app awarded
me a green star, but again, I
don't quite agree with this. I
think I would have felt better
being woken up by my alarm
perhaps at 6:45 instead of 7am
as I dozed off again until 8am.
I
had fallen asleep swiftly
according tot he chat, after reading
in bed for half an hour or so.
According to the Fitbit, I had
over than 1 hour of Deep
sleep, more than last night, and
again more than 5 hours of
light sleep (pretty much the
same as last night).
I wondered yesterday if more deep sleep
would benefit me, but it appears
how I woke up was more
important.
I
did my usual morning routine of
first getting a cup of tea and
reading for an hour before going
out for a run.

This
run was in the opposite
direction to yesterday's. It was
a reasonable run but I made
extra effort at the end to do a
sprint finish to see how high my
beat would go... higher than
yesterday! Yesterday it peaked
at 162 bpm, today I got it up to
173 bpm. The average was also
higher at 155 bpm compared to
yesterday's of 144 bpm.
A
little while later I cycled to
my sister's house, but the
Fitbit failed to acknowledge
that activity and log it. There
is, on the device, the option to
manually start and stop (and
pause) an Activity. From the run
above it can be seen that the
automatic logging starts
abruptly, whereas yesterday it
started more smoothly. It
therefore appears it would be
best to manually start and stop
the Activity logging.
After my visit I continued on to
a shop, and then a continued on
to complete a 13 mile route.

I
didn't have much energy for
today's ride and I mostly
plodded along, putting in some
effort where I could. This is
reflected in the green sections
of the graph along with the 98
avg bpm and a peak of 149 bpm,
compare this to yesterday's ride
of a similar distance with 125
avg bpm and 170 bpm peak. Only
the latter third of yesterday's
ride showed large portions of
"green", although I was still
peaking up into the red and 170
bpm.
I
feel like my night's sleep could
be partly to 'blame' for today's
result, but also I ate a large
meal before the ride, and
therefore this ride is usually
of a similar pace.
Since I'm not interested in
"fat-burning" but more about
improving my cardio-fitness, it
appears the kind of run I did
this morning (20 minutes) was
more beneficial in this regard
than the longer ride I did (1
hour). I have come across
research that echoes this. A
counter argument is about effort
and enjoyment; it takes effort
to sprint, but once I'm out on
my bike I'm quite happy plodding
along for an hour, and feel good
after the fresh air.
