exercise part 2
I sorta repeated my experiment again today. Much higher intensity. At no time was I in danger of going low, but it turns out bonking doesn’t necessarily mean going below 70 
First 30 minutes were relatively low gear, high cadence (avg cadence 99rpm, avg HR 156bpm, avg speed 17.1mph)
00:00 BG=147, started ride
00:15 BG=116
00:30 BG=89
Second 10 minutes I increased the incline on the bike, went up a few gears (avg cadence 90rpm, avg HR 163bpm, avg speed 19.6mph)
00:35 BG=81. Close to bonking here, legs getting really heavy, drank 7g CHO.
Last 5 minutes I cooled down (avg cadence 70rpm, avg HR 144bpm, avg speed 11mph)
00:45 BG=90
Felt fantastic again, although I’m clearly out of shape (figures, heh). Now I’m off to eat a ton.
Glad to hear you are back in the swing of things after your disastrous pre-Christmas adventure.
Bonking happens when your glycogen stores become depleted. When this happens your risk of a dangerous low is much higher. During a mild to moderate low, your liver will be stimulated to release glycogen. If there’s none left, your sugars will drop faster.
Sounds like you’re being careful here and are replenishing things with lots of carbs post-exercise.
