    Gettinng better, but I keep getting reminders that I need to do sufficient rehab still.

    It carried me through a 40-miler OK to 13th place. Yesterday thouhg on a 14km run slightly faster than HM pace, I could feel the achilles at about 10km, so stopped at 12. 12 days to go, so I'll ease off the running and up the rehab - should hold out.

    How did everyone get on yesterday?

    I finished in 1:58. :)

    Finishing BG was 7.1 and no hypos!

    Running the half marathon proved to be a real challenge for me. As some of you already know, I take injections, so my experience may be quite different from those using a pump.

    The main difficulty on race day was dealing with the effects of adrenaline before the race actually started! Adrenaline really seemed to kick in early on, far more than I'd expected. In the morning my blood sugars looked like this after starting off with cereal as usual and taking my normal insulin dose at 7:30am (which I would normally reduce a bit for a long run):

    7:30am - 5.9
    8.30am - 12.4 - took 3 units fast acting as a correction. No trace of ketones.
    9.00am - 19.8 - Eek! Took another 3 units fast acting. Still no trace of ketones.
    9.30am - 16.6
    10.00am - 13.1
    10:15am - 12.2

    At 10:15 I actually took on a little lucozade, as I already know my BG typically drops a lot in the first 5k. I've seen it drop by as much as 8, but have found that starting at a lower BG (10-12 is ideal for me) and taking on lucozade just before the start has been the best way for me to reduce that drop and stay out of hypo danger.

    On a morning where I'm not running, I've been starting on a BG of between 5 and 6, and BG into mid morning and afternoon has generally been between 6 and 8, I can only put the morning race day BGs down to pre race nerves!

    From 3 miles onwards I started sipping from a runners bottle of lucozade. This lasted until 6.5 miles in. I had a couple of dextrose tablets at 7 miles and then 7.5 miles.

    Now something interesting happens from 8 miles onwards for me. My BGs still drop, but they drop significantly less. I think this suggests adrenaline is at work from this stage. I've seen it during the training, even when I'm running at a slower pace. 1 dextrose tablet every half mile is now sufficient to keep my BG steady. (All the more reason to keep a relatively steady pace until 10 miles, really had to watch not to start out too quick!)

    At 10 miles, I picked up a bottle of lucozade sport from the drinks station and started pushing the pace. I took on about half the bottle before eventually chucking at 12 miles. (The dextrose tablets I had plus water would have been sufficient, I just find lucozade sport easier from a hydration point of view.)

    Just after the race, I actually inject insulin again, as I've found BGs go unacceptably high if I don't do this after a run of longer than 8 miles.

    Around 2 hours later, and as expected, I really need to eat to account for all that extra insulin I injected earlier. BGs held at around 4.9 for about 3 to 4 hours, despite taking on 12 CPs uncorrected during that time. Eventually my BG went up to 11.3, and held there, taking me out of danger.

    Long story short, testing before and after exercise is really important!

    Great write up @zicksi101

    Only just getting round to my write up. Yes, managed the run yesterday. What a fantastic day, and no issues with my diabetes at all.

    I came 785th (ish) with an official finish time of 1hr 35m :) ...... (my GPS says I did in 1hr 33m. not the official results, but it gives me bragging rights on Strava.com - haha)

    Here's my race on Strava with route details and km splits etc
    http://www.strava.com/activities/203510289?ref=1MT1yaWRlX3NoYXJlOzI9ZW1haWw7ND01MjY1NzU1

    On the Diabetes front, I'm on injections too, and settled into a nice routine during training to deal with the highs/lows. My race day went as follows:

    (Night before, usual 12 units of Lantus at 8pm)

    Race Day
    Up at 7.10am - BG 4.4 mmol/l
    At 7.20am - 4 units Novorapid. Ate a Sci Mx Protein/Flapjack bar and had a pint of milk (Total 60g carbs - I need 1 unit Novorapid per 15g carbs)
    10am - ate a banana (15g carbs) - no insulin
    10.30am - BG 9.8mmol/l
    11am - Race starts
    11.10am - Maxi Nutrition Viper Boost Gel (25g Carbs)
    11.30am - Another Gel
    11.45am - Few sips of Lucozade Sport
    12.00pm - Another Gel
    12.15pm - Few sips of Lucozade Sport
    12.20pm - Another gel
    12.35pm - Race finish

    12.40pm tested BG - 9.0mmol/l (higher than I expected, and higher than most of my training run finishes - adrenaline maybe?)
    12.45pm - Milkshake and protein bar - 90g Carbs - 6 units of Novorapid.

    4pm - BG was at 4.4mmol/l

    Went for a celebratory meal afterwards, and a few pints. Felt a 'little' hypo knocking on the door as I waited for my meal in the restaurant, but started eating at that point, and felt fine the rest of the day. I cut my usual meal time dose by 50%.

    Bed time reading 7.1mmol/l - had 5g of carbs at bedtime.

    Morning after reading 3.9mmol/l - close call ;)

    Very well done @Adamski ! That's an excellent time, certainly under the 1:40 mark, and great to see you handled your diabetes really well!

    I really enjoyed the race. Found the race a lot easier than the training for it actually! My longest run in training was 12.5 miles, but most of my longer runs were closer to 10 miles after increasing my mileage.

    Some good detail there to include km splits, nice! I finally got round to checking out my mile splits:

    Split Time Distance Avg Pace
    1 8:55 1.00 8:56
    2 9:08 1.00 9:09
    3 8:48 1.00 8:48
    4 9:08 1.00 9:08
    5 9:03 1.00 9:04
    6 9:50 1.00 9:50
    7 9:07 1.00 9:08
    8 9:13 1.00 9:14
    9 9:13 1.00 9:13
    10 8:56 1.00 8:56
    11 8:47 1.00 8:48
    12 8:48 1.00 8:48
    13 8:31 1.00 8:31
    14 1:22 0.19 7:20

    I had a toilet break before hitting Mile 6, which accounts for a slower pace at that stage.
