It's 175 over two days - should have mentioned that. Reminds me, I need to sign up for the ride. I completely forgot to do that.
Yeah, I never go on personal marathons. The 30-60 minutes of riding per day is more than enough to prepare me for a sportive. The last time I tried to run, I got really sharp pains in my shins that lasted a few days. Maybe shin splints? My being overweight could have contributed to it though. As I drop my excess I'll be incorporating more soft-surface short sprints into my HIIT sessions to help recondition those shins.
Ah OK. Still a reasonable push. And yes, signing up for stuff helps.
Yes, sounds like it could be shin splints. You need to build up running time & distance really slowly to prevent them from happening. It's annoying because cardio improves a lot quicker at first and it's easy to think "OK, this is getting easier" and then go out and muck up knees/shins/etc. 1st time I tried running as an adult, back in 2006ish, I did exactly that. My knees took months to get over it and I knocked the whole thing on the head. Losing weight is also good. I'm ~12kg down on what I was 2 years ago and it makes a hell of a lot of difference, especially over longer distances.
EDIT: Also good shoes. Another learned lesson on my part.
Bike's good as it's low impact... well, until it turns into very high impact I suppose! I had 2 good offs last year, the Audi was the 2nd, the first was misjudging a corner and ending up in the gravel. That involved hospital and my left knee looks like the surface of Mars!
Raced the 10k yesterday, mainly to see if my marathon target was doable. It is, I think, but will hurt. Strava said that I did 10k in 48:15 which isn't too bad for an old git - only 1, maybe 2 people older who were faster. Just missed my target of 48:00 but I'd forgotten how painful the long shallow climbs on that course were. Semi-bonked and lost that time between 7 and 8k, more lessons learned, and it's all good.
I smelled godawful by the end of that. Probably unpleasant to share my bus home with even after I'd blasted deo down my pants!
