Why is it ...

That I can cycle 100km without an issue, but almost pass out after 1km of running?

Just started to jog there tonight as part of a new fitness regime. Almost killed me.

Because you dont have running specific fitness it will take time the good news is that given your fitness base it should be easier to adapt quicker.

Also maybe the pace was too fast for your first day out? build slowly and it will come to you dont worry

Keep it going

+1 on that. Too fast will kill you every time. Slow it down and enjoy!

Thanks ecoli. However I found a slower pace to be more exhausting than the quicker. Not to mention to strain it put on my legs.
Trying to avoid shin splints this time around.

My previous post was slightly misleading. I should have said "due to my crappy technique" the slow run was more exhausting.

Was in exactly the same situation eartly in the year. Have always cycled and mileage was never a problem on the bike but running would hammer me.
Went out with a group a couple of times and took my mind off my breathing, after a couple of weeks was able to start increasing the distance and pace.
One key benefit I found was my cardio is far stronger on the bike now Did a few SwordsCC club bike races during the summer and it really stood to me on the climbs.
As above stick with it.

Velo Bro!

Work on your technique now at a slower pace, it gets harder to change later.

What works for me is keeping the same cadence (in the range 85-95 footstrikes per foot per min on the flat) but shortening my stride and concentrating on mid-foot strike. Obviously there is a lot more to running technique than that but its a good starting point.

Make sure to run on your toes to avoid shin splints and other injurys. Was plagued with niggles and strains for years from landing on my heel first, switched there about a month ago and have been injury free since. Wish Id known when I started running

p.s. your calf muscles will hurt for the first few weeks but then you get used to it.

I would start out slower. But remember when you start off running you are going to hurt so even if your body is tired you are just going to have to suck it up and say "f*ck it' and keep going. I still have to do it and i have been running for 12 years.

Depends on a few things really, if you carry any extra weight I always feel it more when running then on the bike, could cycle a long distance when over weight maybe very slow, but found running some much harder with extra weight.

I don't think you actually mean "run on your toes", maybe land on the ball of your foot, I would prefer mid-foot, but never toes - it will be more than your calves hurting if you run on your toes.
There are whole books, never mind threads and articles written on the subject of foot-strike so can't do justice to it here.
On the other hand there is a lot to be said for the "just get out and run" philosophy!

It certainly did! Are you doing much running/biking over the winter VB?

Obviously, to anyone who has been running for a few years but if I say mid-foot then the natural inclination would be to heel strike as the calves get tired... which is why I say toes.
