I'm gaining leg and upper body strength from doing weights again so I'm okay there, and I don't have any other issues.
I think it might be asthma, last night I did some intervals and it felt like the air was very thick and I was using a lot of energy to breath. I wasn't wheezing, but after the workout I noticed my chest did perhaps feel a little tight.
Hi, I'm 42 and have been running consistently for the last 6 years and the last few years my performances have been 5k - 18:47 and 10k 39 mins etc. Up until my Marathon several weeks ago I was running well, 4-5 mile reps at 6 min/mile pace and doing good tempo and long runs. After my Marathon, that I completed in 3:23, I am finding it really hard to run at all. Despite feeling healthy and fit, although do feel a bit tired, for the last few weeks I'm getting massively out of breath just running one mile at a steady pace. I've noticed even at rest I am breathing more than usual. The thing is, before this issue my breathing was always pretty light, in fact I've had a few people ask me "are you breathing?" when I've been running. Three weeks ago I started topping up my iron levels in case I have an issue with that but I haven't seen any improvement. Does anyone have any ideas or has anyone experienced this? I'm wondering if I should see my Doc, however I'd feel pretty stupid asking about a fitness issue when I otherwise feel fine.
Art of Running Faster by Julian Goater - fascinating book that really gets into the mind of the author. He seems to be very open about his experiences and training. Following his advise I got a really excellent PB in a 5 mile race. The tip I took from it and planned was to do 2 sets of intervals the week before a race, 5x1 mile intervals at target race pace on the Monday, 6x300m sprints on the Wednesday, slow 4 mile run with quick and quiet feet on the Saturday, and race on the Sunday. It did the job for me!
Just wanted to report back the advise from the guys above I'm pleased to say is starting to pay off! For the last few months sinse I've been injury free I'm doing 1 set of intervals (either 400's, 800's and 1600,s) sometimes doing them on the track, grass or treadmill, 1 tempo run and a long run (usually!) and just yesterday I did a 5 mile race that would have knocked off a decent amount of time had it of been a 10k race.
Also, on top of the new plan I've read a running book (dare I mention it's name...), but it had a good section on running form...so that's given me something new to work on.
I'm very grateful for these forums and so many helpful posts. Always seems to be something new to learn about running!
First thing I do now is wet the sensors and put the strap on, well before getting changed in to my running gear. By the time I warm up and start my Garmin, I now get sensible heart rate readings from start to finish.
