New 1k best

This evening's interval session allowed me to record a 4:11 minute km. Unfortunately I didn't align myself well with the Millhouses 1km segement so no improvement there (oddly Starva has me at 4:14 for a km but Garmin Connect at 4:11). I couldn't have gone much further at that pace, but might have reached the end of the park if I'd really tried. Something for another day.
