I've upped my weekly kilometres to 40k last week. I did some speedwork today. 7k total.
1k warm up,
1k fast (4:00),
1k recovery,
1k fast (4:08),
1k recovery,
1k fast (4:09)
1k cool down.
When I returned to running this summer, a fast run was around 5:30 min/km. It took me quite a while to get under 5 mins for 1 km and much longer to extend that and get my 5k time under 25 mins. Now, a few months later, a quick run averages around 4:30/km and my easy pace is 5:30/km. I'm the fittest I've been in years.
It's exciting to break a 4-minute km, and I'd love to achieve a sub-20-minute 5k. I felt like I was bombing it on those three quick intervals today, and going even quicker than that for 5 consecutive kilometres seems almost impossible right now!
Does anyone here use the running track at Crossford Bridge in Sale or in Stretford, where the park run is? I think it would be easier to improve my speed on a track rather than worrying about traffic/old ladies etc.
