Maybe I was a bit too enthusiastic the other week and got carried away with the miles as I'm now suffering the consequences. When I first did the canal run into work three weeks ago it took me 50 minutes. It's now taking me 53 minutes. My average heart rate on these runs has also dropped from 139 to 127. That suggests to me that I've overcooked it in the previous weeks.
In the three weeks coming back from injury I did 40km, 40km and 81km all at 7 min mile(ish) pace. Previously I hardly ever did more than 15-25 km a week (and still somehow managed sub 90 min half marathons) so this was a big step up in mileage (kilometreage?) for me. I think I need to be a bit more realistic and focus on the quality rather than the quantity.
Also, I'd stopped enjoying it. In the last twelve years at home I've not run the same route twice thanks to the plethora of paths and bridleways around us. On the work run I was running the same boring route 4 time a week.
Regarding the 7-day heart monitor. I handed it in on Monday and have not yet heard from the hospital, unlike the last time when they rang me up the day after. I reckon no news is good news.
