Every week in the UK (and elsewhere) ParkRun organise free, timed, 5K events in local parks on Saturdays at 9am: https://www.parkrun.org.uk/
This represents a great opportunity to re-test my running threshold/zones in a ‘race’ environment, and to get more experience running in race conditions (I feel that after a year or two of 80/20 and training on my own, I need to re-learn how to really push under race conditions).
I know that I should replace the hardest workout in each recovery week with a threshold test on my Marathon Level 1 plan. That typically occurs on Friday. Is it OK to instead do Satruday’s foundation run on Friday, and do the 5K race on Saturday in place of the hard workout, and still do the weekly long run on Sunday?
I don’t want to make it complicated, but it’s a great opportunity to re-test zones!
Thanks
