Been running for a couple of months now - prior history before these months is basically occasional jogs under 5k so nothing serious.
I am working towards a half marathon in October and trying to understand a realistic goal. I think I've possibly been on the verge of training a little harder than advised in this period I've been pushing to run more 'properly' but I've been taking breaks when excessively fatigued and generally my body feels fine.
So far I have pushed my distance out to 12k with long slow runs, increasing by a km each week and have been practicing breaking 5k PB and 10k PB (the latter in the past couple of weeks only as my distance has gone up) each week too. I've also been doing some fartlek and recovery runs when semi tired.
I am seeing both my 10k times and 5k times come down at quite a rate (10k now at 53:18 and 5k at 23:19). Most of the training plans I have seen mention focusing a certain part of longer runs at 'tempo' pace as well as not going too hard too often, but I am finding it hard to judge what should be my half marathon goal pace given the fact I am eating into the shorter PBs every week, and I do as well enjoy the challenge of pushing myself with these - very motivating to get out there and run.
How should I be working out a goal pace, I suppose is what I am asking, and at what point should I force myself to stop trying to 'race' myself at 5k and 10k distances? I am early 30s and weigh an okay amount.
Thanks in advance!
