Also ran a half yesterday (but not my first of the year). I’m not even close to PB (1:50) pace at the moment, but I’ve given up caring. We threw in some trails to make it more interesting, but yeah, the last couple of miles, despite being mostly downhill, were a slog.
If I can get round the Richmond marathon at the end of May in under 4.5 hours I’ll be ecstatic.
