So far it’s been about 6 months since I started on the
Insight pump and I’ve put in quite a bit of hard work in learning how to trim
the pump to trim the pump for exercise. Learning the timing of run vs bolus,
how much to reduced bolus for imminent exercise, use of temp basal in terms of
scale and timing of reduction etc and it’s starting to pay dividends, to the
point where I can now consistently manage a 10km run or hour bike session on
little to no additional carbs, typically 10-20g and I’ve managed one session of
an hour and 15 mins on the bike with no carbs at all.
With an eye on the Autumn ultra marathon in the plan, I’ve
started to up the length of longer runs looking at getting back to ten
miles/16km for now and then building from there. I have to say though that it’s not always
going according to plan. Overall the legs,
feet, musculature, achilles are all still feeling good and I think I’m being
more proactive in massage and mobility exercises which will help. But sometimes despite all that it just
doesn’t quite work, and it’s those failure that are sometimes the most valuable
learning points.
Take an example of a recent run after lunch. The lunch was low carb so no bolus taken and
the basal was being managed as expected.
Al that done, I set out on the planned 15-16km run intending to keep an
easy, steady pace with a low-ish heart rate, but it never felt right. Worst of all I felt sick, had to stop two or
three times at the side of the road and nearly threw up, I really couldn’t
stomach the carbs I needed to take onboard.
I did need to stop for the toilet twice – lucky for public toilets, the HR
too high, pace too low, and for the first time in over 6 months developed a
stitch. Overall one of the worst runs of
my life, and I contemplated finishing it early more than once, but eventually
stuck it out to 14km. Looking back at it
there is nothing specific that I can lay my finger on in terms of activities
before it, and the only thing I can come back to is eating too heavy a lunch
before the run
Contrast with next few weeks where it all went swimmingly,
and last week with 5 days consecutive, totalling 32 km run and >160km on the
bike split over 5 sessions. So what was
different? Not really sure, maybe just
taking a bit more time to prepare, I probably had a bigger gap between eating
and running by just an hour or so, and maybe that made all the difference. More
experimenting needed I think
I’m also starting to plan for my holiday where I’ll be
taking one of my upright bikes and trying to get at least two decent rides in,
so that’s necessitating training in between. I’m also putting a slightly lower gearing on
it as it’s a bit hillier than the wild Fens, although probably not as windy if
last week was anything to go by.
I've bought myself copies of the maps for the Bob Graham Round as well, starting to look at the route, with a view to an atttempt about this time, maybe mid June next year, but first I need to
make a plan to train/familiarise.
Otherwise, garden is coming on a treat, veggies romping away
both outside and in the greenhouse, and the bonsai are also starting to look
very good again. Here’s an example of a
maple that I’ve been growing for the best part of 15 years, from a
seedling. The overall shape is about
where I want it now, although the left-right balance needs some adjusting and
the trunk needs more time to develop a better taper. Give it another ten years or so and we’ll be
getting there.
This week has been something of an interesting
experience, from a running and diabetes control point of view. I’ve been offshore on a floating platform, so
running on a treadmill which is never the best, but made much more interesting
when that treadmill is also moving side to side and back and forward as the
vessel moves. Diabetes control has
needed a different mindset around the exercise as the evening meal tends to be
early offshore, typically 6pm, which is when I’d normally exercise, so it’s
swapped the order of things around. The
strategy I’ve adopted, reasonably successfully is to do a normal basal
reduction ahead of the run, and minimal bolus at the meal - a typical reduction by 75%, then run about 30-45
mins later before BG has jumped too high.
As usual test during the exercise and take on carbs appropriately depending
on where I started and where I ended up.
Starting at 8.x needed carbs mid run, and ended in the low 4.x, starting
at 10.x brought me down to about 5.x with no carbs.The running this week, more to come at the weekend, was
8km / 43:25 / 5:17 per per km, Ave HR 133, Max 144
10km / 51:26 / 5:09 per km, Ave HR 136 , Max 150
10km / 51:19 / 5:08 perkm, Ave HR 138, Max 150
Those of course are all on a treadmill, I'm not going to do laps of the helideck after all. Today was a mixed on/off road locally and when you take the vagaries of wind and terrain into account, for the same pace the average HR was around 145 over 12km.
