Done 2 before at around 24mins, this morning I went with our Border Terrier what with him sniffing, looking for squirrels, weeing and stopping until I gave him a snack we did it in under 28mins.
But the good thing about Parkrun is that it’s for all, the sprinters the plodders and everyone in between. If you were always out to beat your PB you’ll soon get bored with it.
