They are doing this at my local Parkrun tomorrow (from 20-35 mins I think!). How does it work? Not sure I want to stick with a pacer as I prefer to run with how I feel on the day. Guess I can just do that but will be able to keep an eye on nearest pacer and see what finish time I am on for as I run round. Any thoughts from you experienced parkrunners? I don't go very often as Saturday is usually my long run day. Am looking forward to it🙂.
