5k: 18.33
10k: 38.20
21.1k: 1:22:10
42.195k: 2.50.27 (cool) 2.59.25 (tropical)
Her scaling is quite good off 90k/week. And yes, Bedok Reservoir is tougher to run, so 18.42 is a good time there.
It's pretty good, you probably can run 2.4km in 11 flat or possibly slightly under that
9 mins for temperate vs tropical in reality is insane actually, or 1 min per 4.6km. That means even for 5k it bare minimum can shave us 30 seconds diff over here liao.
Yah good scaling, probably train at that distance majority of the time. 2:50 for FM is 4:02 pace, but then the converse is also true ba, if 5k can only manage something like 19:30 but you are a comfortably sub-3 runner, then........the muscle fibres be like. But of coz, i guess for middle aged folks that could still be a possibility due to age......im seeing on letsrun forums that there are 19:xx sub 3 middle aged runners.
On reddit or similar forums, there are even some 16:xx folks ( not talking about 16:59 lol) who cant go sub-3 even . Of coz youngsters collegiate / cross country type runners who are running that distance more for fun and without specific long distance aerobic training ....also unknown factors like cramps / bone or simi pain / fuelling. You dont train for it of coz bo huat.....same goes for ultra distances like Mont Blanc 175km and humongous elevation gain.
I remember last time we were wondering what 2.4 / 5k timing that sprinters like Shanti can run. heh.......
edit - i gai siao you if you love racing and dont mind a bit of danger (controlled danger), come over to cycling and do duathlons. I think you'd love multi displine sports. Last weekend i came across Quantum racing team @ Sentosa. Not say racing per se, but really the pace is no joke and it's very dynamic in nature, not just racing on PCN kinda condtions. Quite addictive with the adrenaline. There are also other rides that are racy in nature, but involves beating red lights sometimes, so...... better not, not asking you to go those types. Sentosa quite a fair number of fast fellas sometimes that you can meet, coz over there also got triathletes training.
How much cycling can carry over to running, i think we cannot say for sure as it is quite individualised based on so many factors, but lately got 2 good examples in which it works for them. (generally cycling does not really carry over to running much, but we'll never know, esp if the volume is high + there is some specificity in some areas). Anyway, running can carry over more to cycling also ba.
