First off, a very big thank you to Michael for sponsoring me for my upcoming 5K.. it’s only six days away now! Very kind of you indeed!!
I went out for a run yesterday and I decided to try something a little different in order to prove a theory I’d often read about. Knowing full well that when I start out I seem to have loads of energy but usually hold back, I decided to see what would happen if I didn’t. So I decided to run.. not sprint, but run until it hurt then slow down to a jog, then run again. I envisaged doing this for the whole of my usual 5K outing. Ha!
Well, I didn’t do too badly to begin with – I ran pretty fast (7-8 minute mile pace) for probably 0.2 of a mile before I built up an oxygen debt and had to slow down. I jogged at a slightly slower than usual pace for a minute, then ran again.. barely making a few hundred yards. Jogged again.. for a while.. and a while longer. Then tried to run again. Even less distance this time. I felt sick. I jogged slowly some more, now well under pace. I was reaching the halfway point and decided to run the last hundred yards. I barely made it.
The run back from my halfway point? Well under my usual pace.. more like 11-12 minute miles as opposed to the 10 minute miles I am used to. And I felt like I was doing 9 minute miles for the whole darned way back too. My heart rate was way up in Zone 5 (I found from my 10K that I do best with it about 5bpm below Zone 5) as if I was going hell for leather but in fact I was just trundling along. The gains I might have had from sprinting at the start were long gone. If it wasn’t for sheer determination to not walk at all, I would have walked.. I *needed* to walk. The last part went achingly slowly. I had stitch. My breath was rasping. Even my blister seemed to hurt more!
Alas, I cannot tell you exactly what the time difference was, because I also hit “Stop” instead of “Lap” when I started the 5K proper, and did not realise this until I’d finished all my sprints and was halfway through. I think I am not going to bother with “Lap” any more unless I am literally doing laps. It is proving extremely difficult to remove the “pause” from the data even if I add in the waypoints by hand afterwards.. I apparently have an average of over 300mph for that first stint, ha! I know I sprinted a bit, but I don’t hear Usain Bolt’s agent calling me right now.
With all said and done, I *think* I did the 5K in around 30.5-32 minutes. Not as bad as I thought it would be, but I know I can do a *lot* better if I don’t go crazy at the start and just concentrate on a steady pace with maybe increasing it a little in the last half a mile or so if I have the energy. Also, I found it a lot harder going running in the morning – normally I do evenings but I was a lot stiffer and lacking in energy for this midday outing.
Lessons learned:
* Evenings are better
* Moderate and Steady wins the day
* It hurts to do sprint interval thingies; I did not enjoy it
* Don’t accidentally stop the Garmin.. argh!
Plans for this week – One more 5K either tomorrow or Wednesday (trying out the strategy I will use in the race) plus a trip to nursery with the pushchair on Friday. Nothing at all on Saturday. Race on Sunday!!
