Literally sliding down the road on my arse.
60 hours into no carbs, including the first 33 hours fasted and only one meal in the next 27. My morning blood readings were:
Glucose 4.3
Ketone 1.2
Looking outside it was a lovely sunny but cold day. My plan was to have an easy adaptation ride round the 60k datchet loop and then continue the 22k into work. Knowing I am not fully adapted I added some KetoForce to my water bottle. This is a liquid exogenous ketone that I have not used before, but my hope was to up my ketones while I try to adapt.

After Tuesday's ride additional socks and gloves were worn, I took a sachet of almond butter, coconut oil and some dextrose tablets in my pocket. What a lovely day to be out, I turned the page of my power meter so I did not look at my power. This is a truly fasted ride and about adaptation, forcing my body to use my fat as fuel.
I turned down by the river and as I passed the cyclist on the verge I shouted to see if he was ok. 30 meters later I was sliding down the road on my arse. Black ice, it looked exactly like the wet road before it. The upside of black ice being so slippy is the I just glided across it, no tears in me or my clothes. I got up and saw two more cyclist coming I stood in the middle of the road warning not to go left. Clearly the one who just thought I was some nutter was soon on his arse too. This is my first spill off my road bike which I have had for 3 years, if only my MTB record was that good.
After dusting myself down I set off again, I felt pretty good. 30 mins in I tried my ketone water. I am not sure that just putting it in plain water is the best way to consume this, it tastes truly hideous. I have been trying to place the taste, I think it is a cross between fuel and anti nail biting varnish. However that said while on an easy ride it was just about drinkable but I could not face that half way up the Alpe and blowing out of my arse.
60-90min in I felt ok, easy steady pace. Shortly after that it was hard I was mentally wanting to cut the ride short and go home and not to work. 2 hours in I stopped and had an almond butter sachet and the rest of my keto drink, to be fair in the other order so I was not left with the after taste. By this stage things were just going from bad to worst, 10 minutes down the road I was convinced I had buckled my wheel or the brake was rubbing. I got off and check the bike and found the mechanical fault, me, the bike was fine.
6.5k to get home 28.5 to work, the battle was still going on in my head, be strong, think of the adaptation, just do it.
2k to get home, game over. My vision was narrowing (just like the end of all out threshold tests or the end of mega events), I was really aggravated and worried about the traffic around me, I was shaky and not sure I could make it home. I did not have the heavy legs, the specific headache that I normally feel with bonking and hypoglycemia but I was empty, my legs, my body, my mind all of me. I did not even have the thought to eat some of the dextrose in my pocket. Could I get off and walk, not that would take to long, just turn your legs, just turn your legs. It felt like an eternity, Stava says 5 minutes.
I got home, ate couple of leftover sausages and out of interest tested my blood:
Glucose 3.4
Ketone 4.7
The walk to and from the train station was hard but my lunch and dinner tasted good.
I think the exogenous ketone probably did help my ride considering how fasted I was. It appears to have had no negative effects on my gut which is good. This will have to be revisited, there is also a similar power but both these products are very expensive.
