My goal in running is to reduce my blood pressure, and 5 months after beginning C25K my blood pressure had not budged. So I decided to give up alcohol and caffeine. From past experience alcohol would be no problem, but giving up caffeine would be very hard, as I have tried in the past, and found the withdrawal so unpleasant I gave up.
After a few days my blood pressure had dropped to normal - green lights for both systolic and diastolic on the machine I use to measure it. I should have been overjoyed but I found it kind of depressing. All that running, and all I needed to do was give up two things I really love, wine and coffee! On reflection I decided it was the combination of running and abstinence that brought my BP down.
So this last week has been horrible because of caffeine withdrawal. Really struggled to run and for the first time, on Monday, I did not run my planned distance, doing 5K instead of 10K.
I ran 26K last week and I did not want to lose fitness so I decided to run 10K Wednesday and Friday, making 25K for this week. Wednesday was perfect conditions for me, sunny and just above freezing, but I struggled, but made it through the 10K - slowly.
Today was raining and windy and I struggled - but ran 10K in a new PB, best part of a minute faster. So I'm close to achieving all my goals, and I suppose I should be pleased. I'm sure I will be when it sinks in. A cup of coffee would be nice though!
