I recently ran a race in trainers. They weigh 7.9 oz in a size 7 (mine are size 6.5) My spikes weigh 4.4 oz in a men's size 10, and I wear women's size 5 (men's size 4.5?). So the spikes must weigh 3.5-4.5 ounces less than the trainers, right?
In the race I ran the 1600 and 300H, but I'm curious about other distances as well. They're mid distance spikes if that matters.
Depends on times. The faster you run, the bigger the difference spikes make. For example, if you run 38 for the 300mh with spikes, you might run 1.5s slower with trainers. If you run 55, you might only lose a second with trainers. As a percentage, these is fairly large differences.
These are extreme examples, but the point remains: what times did you run with your trainers or spikes?
I'm much closer to the 55 (the record for high school girls 300H is 39.98 so I'm definitely not running a 38 lol), so about 1 second faster in spikes? It was also my first time ever running a hurdles race, after only practicing hurdles for about a week. I wasn't really breathing hard when I finished so I think I can run 1-3 seconds faster based on that + more practice. So 2-4 faster with spikes at my next race? (It's in a week and a half).

Racing in flats etc feels good but you aren't as high on your toes and you don't get as good a grip on the bends. Look at a formula one car come off a bend, they look like they are gripping the corners and accelerating.
The number I've heard thrown around regarding endurance events is 1% per mile per ounce of difference between the weight of your trainers and the weight of your spikes.
go on a diet and lose 3LBS then race in your trainers
