With my new-fangled watch I can actually keep track of my split times for each Km, which is quite funky:
|Point||Interval time||Cumulative time|
I overdid it part way through trying to catch up to a group ahead of me and ended up having to stop for a few seconds just before 4Km, and got overhauled by the group behind me :( Still, it's a new PB, not to be sneered at. It must be said, though, that recently I've been going to the gym, which may well be great cross-training, but it's not a complete substitute for getting out there and putting the miles in. So I need to get back in the habit of plodding around at home, or actually organise myself for plodding to/from Paddington.
