Running on Keto: 20th May to 23rd June 2017

A review of my marathon training. All training is done in barefoot running shoes and on a ketogenic diet.

Firstly I cant believe I haven’t done a Training post since the 19th May. Secondly I cant believe I have done so few runs between the 20th May and 23 June!!! However there are a few reasons (excuses) for the lack of activity. Although I must say the runs I have done, have been pretty high quality for me.

Saturday, May 20, 2017, Run Completed: 13.36 mi ~ 2:09:44 (9:42 min/mi).

This was my last run before the Edinburgh half marathon. I maybe ran it at 95%, as I wanted to push myself to gage what sort of time I could aim for. However I didn’t want to push myself too much and risk injury. After this run I tapered by only doing walks with the wife and dog. Averaging 4 miles a day.

Sunday, May 28, 2017, Run Completed: 13.33 mi ~ 1:54:09 (8:33 min/mi)

This was the Edinburgh Half Marathon. I was very happy with my time, and performance. Not bad for a dude wearing sandals haha. After this I took a couple of weeks off. Allowing me to recover physically but also mentally. In this time I was still walking over 4 miles a day, which I classed as active recovery.

Saturday, June 10, 2017, Run Completed: 13.06 mi ~ 2:11:00 (10:01 min/mi)

My first run after my time off. Ran under MAF conditions. Happy with the run, and I felt good and healthy.

Monday, June 12, 2017, Run Completed: 9.01 mi ~ 1:41:41 (11:17 min/mi)

This run was funny and disgusting. I was doing fine, then I got bad guts half way around. Had to stop in a sheep field for a number two. Then walked/jogged the rest of the way home. So to average 11:17 minute miles was actually pretty impressive!

Wednesday, June 14, 2017, Run Completed: 10.07 mi ~ 1:36:50 (9:37 min/mi)

I knew I was away for a friends 40th birthday party at the weekend, so I squeezed another longish run in. Again I was happy with how I ran and the average pace I set. Then after that weekend I have picked up a hamstring niggle, too much drunken table tennis perhaps. So I haven’t ran at all this week.

I am hoping to do a 13-15 mile run tomorrow. Then taper next week. As on the 2nd July I have another Half Marathon race.

      I train mostly at my MAF heart rate, usually in a fasted state. I intend to run my first marathon in October fasted.
