Started back into training tonight with a very light session on the track. Only completed four six hundreds relatively slowly but that was enough. My 400m lap pace for the first one was about 85s increasing to 80s for the last one. It felt pretty easy but my left ham string began to tighten and I aborted halfway round the fifth rep. I was surprised I was able to go even that quick (or slow depending on your point of view!).
Anyway, I'm back on the training trail after a long layoff of .... two days!
