Sunday & I get a blow out!

Planned a 100k bike ride. Well I got to 30k into it and got a flat tyre. Had that changed in about 10min & was off again. Got to 47.5k when BANG! My rear tyre had a blow out! Well that was the end of that. I tried to ring Dad to pick me up but no answer so I rang Mum. She came to my rescue! I'd done that 47.5k in 90min so was travelling at 31km/hr. When I got home I went into the gym & got on the t'mill. Managed to get 18km of pretty much pain free running. Did 5k slow in 28min then had a stetch. Then did another 5k in 27:30 then stretched again then another 5k in 25:40 then stretched again then did 3k in just over 15min. I was going to do an extra 2k to make it 20k but could just start to feel the hammie so I stopped. Could feel it doing movement when I'm not running like bending over but it felt great running on the t'mill.
