Strength Training, Donating Blood & Other Subjects

 Hi, Friends & Fellow Runners:

As many of you know, I’ve been a regular contributor to a column called EachCoach, published every Wednesday by Canada’s National Post newspaper.  My job is to provide brief, on-point answers to questions posed by runners on an array of topics.  Here are some of those recent questions.....

Am I doing too much strength training and is it hurting my running?
Is there a right time for a runner to donate blood?
How do I eliminate the boredom of treadmill training?
I’m a new runner and already have foot pain; what’s the problem?

.....and here’s the detail:

Q.  I am new to my running group and I can't seem to find a good pace group for me. I'm too slow for one group and a little too fast for the other group.  The faster group pushes me to go outside my comfort zone and that's good, but 3 times a week of pushing yourself hard can lead to injury in my experience.   I have a question about whether I am overtraining and maybe that's why I am slow. I take Sundays off every week. I strength train on Monday and Friday with weights for an hour each time; on Tuesday and Thursday morning I work on strengthening my core for a half-hour and then I run 5 or 6 miles in the pm; on Wednesday, I cross train.   Am I doing too much and is it slowing my running times? I hear how important strength training, core work and cross training are, so I'm trying to include these to strengthen my running?  Any advice?

A.  Let’s cut to the quick and answer your specific questions:  Yes, you are doing too much strength training, and yes, it is slowing down your running.  You should strength train no more than twice a week for a maximum of one hour in total.  More is not better, especially since your four strength sessions seem to be limiting your running to 3X/week (instead of the preferred 4 or 5X), and none of your runs appear to be speed intervals or hill repeats.  On a second point, you’re correct in scheduling strength training and running on the same day, but your running should come before, not after, your strength sessions.  Research has shown that by doing the strength work first (as in your case) your ability to sustain fast times in runs done later in the day is reduced significantly.  

Q.  Are there long distance runners who donate blood somewhat regularly and have they noticed any effects on their endurance?

A.  After the Boston Marathon bombing last year, hundreds of runners made their way to local hospitals to donate blood.  It was their way of honoring the victims of that horrific event, but on a more mundane level it was something they felt they could do because they had run their race and knew they’d be entering an extended period of training downtime.  The lesson here is that timing is critical.  Donating blood hurts athletic performance because it leads to a reduction in red blood cells which transport oxygen to the working muscles.   This, in turn, can reduce your anaerobic heart rate in the first week by as much as 10% and makes your hard training runs immeasurably more difficult.  As well, a full return to pre-donation performance levels can often take as long as a month.  So it makes sense to give blood only during periods of time that allow for several weeks of recovery before the onset of serious training or competition. 

Q.  I’m hoping I can get running outside soon.  Treadmill running is boring.

A.  You can eliminate the boredom by introducing variety into your treadmill sessions.  Mimic interval training, for example, by completing several cycles of five minutes’ sprinting and five minutes’ walking.  Duplicate a series of hill repeats by raising the elevation to a “6” and running hard uphill for a half-mile before cutting the elevation back to zero and jogging the same distance.  Or simply set a pace you want to run in your next race, maintain it for 10 minutes before taking a one-minute walk break and then repeating the routine four or five times.  If you’re watching TV, pick up your pace during commercial breaks.  If you’re listening to music, increase or reduce speed with each new song.  Etc., etc.  The possibilities are endless.

Q. I am relatively new to running.  After my first few weeks, I was jogging about 4 miles 3-4 times a week.  Feeling great overall and was looking forward to pushing further but have come across a nagging big toe/ball of my foot pain that hurts when I push off the toe.  No swelling or bruising, just pain in my left foot and I am now starting to feel it in my right as well.  I’m wondering if there is anyone with similar issues.

A. Footwear is the usual suspect when it comes to pain like yours.  Do your new running shoes fit properly and specifically allow for the swelling in your feet when you run?  And are they made to accommodate the structure of your foot?  Only if you know the answers to such questions are a definite yes should you consider other possible causes.  You might be striking the ground on the balls of your feet instead of the midsole, for example.  Or you could be running too much on hard surfaces.  A final but remote possibility could be insufficient fat padding in your forefoot – a problem that could be solved by placing a foam rubber pad just behind the painful area.
