Thanks again, it's great to see the friendly and insightful responses on this site.
I'm a sophomore in Simon Fraser University (

I very much agree with you all; the 400m will be crucial in determining how much my 800m time will improve this year. I've been doing a some weight training and plyometrics for the first time this year--I'm hoping that will out my 400m time somewhat. I think I also need to work on pacing in the 400m. When I ran 52.8 last year, i hit the 200m mark in 23.1; however, I hadn't actually covered 200m because I was in lane 5 and the outer lanes start ahead of the inner lanes in order to make up the difference in distance around a track. It was more like 185 meters--nevertheless, it was fast for me.
As for my progression, I started running in grade 11 and ran 18:02 in my first and only 5k on the road that year and I ran 2:08 / 4:35 for the 800m/1500m respectively in track that year.
Grade 12: I had a breakthrough season this year. I started off running 2:06's in the 800m and eventually got down to 1:57.6 that year which was the only time I went sub 2 minutes in highschool. It was the hardest race I've ever done in my life so far; I can almost still feel the pain to this day

My 1500m time was 4:11. My 400m time was 53.5.
Freshman in college: In cross country, I was running in the low 29's for 8k--a mediocre cross season. In track, I had trouble breaking 2 minutes all indoor season but eventually I got down to 1:56.1 in outdoors. I think it took me a while to adjust to college training plus the courseload is a lot different than highschool...not to mention most the meets are away from home so you can't eat your regular meals, do your regular routines etc. I think I'm well adjusted to this now. For anyone who is making a transfer from highschool to college, don't be discouraged if you don't make a substantial improvement in your first year. I think Alan webb had this problem.
1500m time 4:05.1; 400m time 52.8.
Sophomore in college: Breakthrough cross country season got me down to 26:49. It'll be interesting to see how this actually affects track performances.
