New to BB, but am a cyclist: is my leg press (quads) 1 RM any good?

[Esperantisto]

Hello everyone.. I'm more or less new to weight lifting and certainly new to bodybuilding.. I'm not actually looking for extra muscle, but for less fat, which is why I took up a body builders diet (Cyclical ketogenic diet) and also took up an interest in weight lifting in order to diminish BF% and become a better cyclist.. I'm a long-distance cyclist who somehow can't combine strength with endurance.. I can plod on for hours on end, but at turtle speed..
This is why I was a bit surprised today!

Today I was doing back, shoulders, calves and abs. One of the abs exercises is on a leg press. Today I had to wait so long for the leg press that I did other exercise first and used the leg press last.
As we had been discussing how to try out a 1RM before on a Dutch bodybuilders forum, I was tempted to try out how I'd fare with the regular leg press (for quads).

Well, it seems that I'll need to abandon the leg press soon and will have to start squatting.. I've decided to go for the front squat (no problems falling over backwards because of short tendons I hope!), probably with a very light weight to test the waters (have shoulder probs).
Why? Well, it seems that since I've been lifting weights fanatically only for 3-4 weeks in a row now and I'm nearly maxing out!

My 1RM was 250 kg! I was flabbergasted! Or isn't it much of a big deal? I have never seen anyone do 250 kg on a leg press before..
How I did it.. I knew I could do 160 kg as that was the finishing set weight of last Monday (10x100,6x120,6x130,5x150,4x160.. I hadn't been in the gym for 3 weeks, but after all those puny but steepish Portugese hills my quads were well trained).
Anyway.. I started with 170 kg, then discovered it felt easy, and put on 190 kg but when I moved the plateau, I thought I'd be able to do 210 kg.. same for 210, same for 230 when I finally tried 250 kg and just managed to push the weight back and decided this had to be my first established 1RM weight! Yooohoo! I should be able to surpass this fairly easily with a bit of training, shouldn't I?

Was this a right way to find out what my 1RM could be? getting the 'feel' of lower weight but not tiring the muscle by not completing the movement?

And most important of all.. how does this compare with what other female BBers can do for leg press? Is it good? Or just average?

At least I'm quite excited about it.. now I hope my knees won't complain too much!

250 kg, thats about 600 lbs give or take a few. im 19 and lift daily ive never maxed on leg press cause theres not enuf room on the bar, i usually do around 850 for 12 reps but ive seen kids as young as 15 doin 600, so its not that big of a deal, and u being an athlete anyways should be able to do more than that, next time try maxing before doing any other exercises so u dont preexhaust your quads. Keep lifting youll get there.

Unfortunately it was not a valid number.. I asked advice again today on how to exactly do a leg press and I wasn't close enough to the platform... so now the last set with 140 kg (6 reps) was a struggle. Sorry! Got a bit too excited about an improperly performed leg press!

I'm quite weak in my upper body on the other hand and started trying out the sumo squat today (last exercise of all).. i did it with 25 kg . Just to get the hang of it.. I have decided to do sumo, as regular squats are not feasible as I have very short achilles tendons.
