My best run this year was 20.21 in April at Dulwich Park (the parkrun course where I set my PB back at the end of 2013). Was pleased with this as was a very blustery day. Recently set a PB at my home park (20.52) which has a tough uphill section around the halfway mark.
Most enjoyable race I've done recently was the City Of London Mile which I did in 5.55 though got held up quite a bit early on. Subsequently did a mile time trial at my local track in around 5.45 which most online calculators suggests a sub 20 5K is possible but who knows. Had never raced over a mile until recently and really enjoyed it.
Will be looking to have a go at a sub 20 5K soon either at Dulwich parkrun or maybe at one of the 5K evening races in Battersea Park in London which is one of the fastest courses in the country. Will choose a suitable day when its not too hot.
PS Took part in a local relay race over 3K last Wednesday evening after a day in which the temperature in London & the SE was around 36-37C. Had cooled off a bit by the time I ran but still very warm and humid. Found it really energy sapping especially as had to run two legs. This hot weather is great for sitting down with a cold pint but not so good for running.
According to the McMillan calculator, I should be capable of around 5.50 based on my best 5k time.
I was at the track last night with my running club and the session was 2 sets of 4 x 800 meters with 60 secs static recoveries and a lap jog between sets. The group I run with are in the rang of 19.30 - 21.00 mins for the 5K and for the first set and the first rep in the 2nd set I did in between 3.10 and 3.12.
Was feeling pretty good so decided to speed up for the last 3 reps which I managed in 3.03, 3.00 and 2.58 so maybe the Macmillan estimate is not too wide of the mark.
Will get over to the track soon when its fairly quiet and have a go to see what time I can do.
I mostly run 5k's (parkruns and other 5k races), a few 10K's and have done a couple of 10 mile races.
Have entered the Westminster Mile race in May but have never run a competitive mile race before.
Have been searching online for the best 1 mile training but the info seems a bit sketchly? Something like 400 meter reps on a track?
Also have been trying to get an idea of what sort of time I should be shooting for based on my best 5K time which is a 20.09 but have got significantly different results from various on line calculators.
