Sore tum!

I'm a day ahead on my training schedule, yay! Admittedly I skipped a session last week but no point remembering that, onwards and upwards is the way to go. Today is rest day (apart from the ever-present core stuff), but yesterday I did a particular favourite session: hills! Pretty standard really, schedule said to do 3k warmup, 8-9 reps of 45 seconds up and walk/jog down, then 2-3k back home. My hill is pretty bang on 3k away from home the long way, and with a shortcut it's 2.5. I did 8 reps, jogged down most times, walked one, put the brakes on once and tried to run fast once. All this with a camera pointed at me - I'd placed hubby halfway up the hill to take some action shots so I can see what I do wrong so I can work on it, and what (if anything!) I do right... Then I did a run til you puke-lap. Not literally of course, more like can I run at full speed all the way up? - the hill is only 110 metres but it's hard work for my little sausage dog legs! And yep, I made it (with only a little cough at the end...), and shaved about 10 seconds off the previous laps as well. After doing situps two days in a row I am a bit sore. Right where the bra strap - and pulse band! - sits. Nice. Why not round the middle, where it's needed?
