Ok, being new to all this fitness, and running, and biking, and swimming, and wot not, I set my target at a conservative 55min for 10km (my best being about 57:35 ish). I haven't really being paying attention to times cos I been concentrating on getting volume up to a level. Anyway, went on my (short) long run of 10 mile today, as it was a reduced volume week I thought I would time the first 10 km to see what level I was at. I managed it in 53:39, so not fast by any standards, but still knocked some time off my best and under what I was aiming for. I have now updated my target to 52 min, is this still too conservative, or is it ambitious to make those gains in a month. I don't want to push too hard as I am having issues with my patellar tracking, so am back and forth physio. Ref the run today, I would say it was pretty close to all out effort, started retching at 9 km and my pulse was around 180 bpm for most of it, my max is 184. What do I think?
