Apologies for not keeping up on this! I'm still working hard though. Running everyday and lifting almost everyday. Nothing much to write about as I'm in sort of a general exercise phase. The only intensity I've done running is hill bounding and tire pulls. I'm finding hill bounding to be both fun and incredibly dynamic and it took me a couple of sessions to get it right. I do them on a ~15% grade and find that just 6-7 bounds (per leg) is plenty. The tire pulls I'm not timing or even really measuring, although I know which tree to start at and which tree to stop at. All is well.
