In this week's slightly delayed episode we workshop some ideas of different ways to run 5k at parkrun - other than a flat-out PB attempt of course! Meanwhile, Lisa runs 10:46 for 3k, spikes her HR above 200, and collects some much needed data for review by her cardiologist. She also outlines Brian's penalty options for losing the 3k/5k challenge. Down south in Ballarat Brian's fitness has finally arrived and he's running longer threshold sessions while toying with the idea of one last gasp effort to break 20:00 for the 5k before the end of March. He also spends some time reflecting on the health of the aerobic system in contrast to building a bigger aerobic base, personalising HR formulas, and including more threshold runs in his next block of training.
