50m to 100m problems: Endurance or Track problem

Hi all, Just having some strange problems. I’m turning 17 this month.

I ran some 50’s the other day. All Legit, on a hard dirt track, No wind at all: These are hand times, but they are very accurate. First two were when coach put another athlete 10m in front, and I had to catch them. Third was just by myself.

#1: 5.91 <----- coach was getting excited
#2: 5.78 <----- coach was dumbfounded…there were no timing probs and distance is perfectly measured.
#3: 6.10 <------ 1 minute after 2nd 50, by myself. He said I run much faster when someone is in front of me…but I felt tired.

Now today on a different track (very soft, uneven grass track): Very cold afternoon…

I did

 50m: 6.17

#1 100m: 12.05
#2 100m: 11.98

My coach said he can’t see any deterioration in my speed over last 50m but my time says otherwise. He said it was probably the bad track.

Haven’t done many 100’s lately, but last years PB was 11.28(e). I’m really trying to figure out what has happened here. Coach keeps telling me its the track. (we can’t do 100’s on the dirt track as it is only 80m long.) I’m just trying to figure out whats happening. Even if I had bad speed endurance which coach says I don’t, I couldn’t possibly lose that much speed over the last 50m. According to those times, its taking me like 6 seconds to cover last 50…I don’t think thats right. On the dirt track…wouldn’t 5.7-5.9 for 50m come to 10.5-10.6 for 100m?

I know of another athlete from armidale (Jay Stone…much older than me) who runs 100m: 10.7 200m:22.10.

When he recently ran on same track I ran on today he did 100m: 11.8 200m: 23.7

My coach is going to get me to do some more trials through the week and he is going to film me so he can get my splits, but I wanted to ask you guys what you think? you think this is the track or me?

Relax - Don’t worry about it til you get timed on a decent track - sounds like the other guy had the same problems.

i agree with gloop. Running on grass is always much slower for me (slow enough i only use times to see if i am gropping off).

Maybe it was his timing.

Your 50m times on that dirt track were pretty good. I remember reading about this drill that was supposed to help 100m runners that finish poorly. What you do is time the last 50m of a 100m run then move up all the way to the last 90m. Also it might just be early in the season the track might be bad or your conditioning is not in place. When you get to a track meet with good weather and a fast track post your times.

Later

I need to work on my 100 meters finish…anybody have any info on this?

I’m gonna time my 100 meters this sunday possibly at a track in spikes…no blocks though…ive never timed it so this is probably a good idea :cool:

Edit: just saw a thread with some advice on this…but anybody with any other info post it please
