Is this a good speed endurance program. I also want to add plyometrics, but do not know where.
What are you asking about?
Sorry about that. I had an attachment, but it didn’t show.
The download file has the extension .xlr.
Microsoft says that means it was created with Microsoft Works, which not too many computers have these days. I do not, and cannot open your file.

I guees we need a little more info…
What are the intensities of the runs (especially the 300, 200, 120)?
How much rest inbetween?
Are the 300 and 200 tempo runs at < 75%? or intensive?
Whats the difference to the tempo you introduce in weeks 3-5?
What level athlete this program is made for? (Current PRs)
What time in the season this plan is meant to take part?
Are you really doing just 2 weeks GPP runnig tempo only (6 toimes a week?) and then 3 weeks sg like acceleration/tempo/SE/tempo/SE/tempo?
What do the 10x30m mean on line 2? are they part of mondays workout, part of the rest or day 8 of the week? 
For the 300s and 200s in the conditoining part, the point is to finish the amount of volume, like 8 of them. So as the volume gets lowered, the intensity increases. The 120m are ment to be SE, and are at 100%. The 10x30m is part of mondays workout. The workout is for me. I am turning 15 in July. I ran 13.1 in 110m(at the time we thought it was 100m), first reaction. My goal is to run 11.8 by november. This program is for the off-season, and i am planning to do a top speed program after this.

I don’t know personally I’d not recommend that form of conditioning as I do not see any benefit. It must lead to complete fatigue.
Week 3-5 seem ok to me.
Generally I do not believe dropping your times from , lets say 12.2 to 11.8 is a matter of Speed Endurance.
Others?
It might be. He’s probably not accelarating past 40 meters at the most. After that point he would decelarate to the finish line. So he would probably have more room to improve on SE than a sub-11 runner would.
thx for the comments. What do you suggest I do for conditioning. Also, should I add plyometrics, or weight lifting, if so, where?
No question, beginners accelerate for a short time an decelerate for most of the distance, but I still think general conditioning and improving strength might be the main points a very young athlete around 12 sec 100m time should concentrate on.
With younger athletes I do a lot of hill work on grass, almost all year, except for 6-8 weeks when their major comps take part - I really believe in it (and that athletes up to 11.50 can improve all year round by GPP-style training) and do a lot of stuff uphills (less than 10% incline!) like:
Acceleration for 5 or 6 seconds
plyos like uphill runnig bounds and single leg hops
15-20 secs uphill for SE
Short cycles like 3x3 weeks (first 3 weeks mainly hills/tempo, last 3 weeks focus on more track workouts, 3 weeks inbetween mix) and repeat…
But the more advanced the more you have to introduce specialized track work and think hard about periodization and put all these general GPP-like stengthening into GPP only).
But I guess that limit is somwhere between 11 and 11.5 secs athletes…
