Back in first, and this time with the right settings
1260 finish
Yes, the pyramids are pretty essential in this game. I restart until my capital has stone or gold. This time it had stone. I popped mysticism from a hut, other than that I followed my tech path in previous posts. Getting a prophet for theo then using the Oracle to get paper is the only advantage I think I have on you. It shortens your tech path a lot. I received 6 GP total. prophet (theology), prophet (code of laws), prophet (civil service), scientist from physics (electricity), 2 engineers (UN). I received my first GE with 4 turns left on mass media. I had another GE working but was like 15 turns away. So I put enough artists specialists in to get a GP in 4 turns. I sent my first GE to that city. He arrived as mass media finished and I popped another GE that turn

Worked out for me.
I think I played pretty well. The only thing that hurt me was that I originally had 7 cities but then found a river spot with 2 food resources, gold, and lots of flood plains. I founded my 8th city really late and was going to make it a GP farm. I didn't need it and I think it cost more than I made off of it. I popped a GP 2 turns after I built the UN.
The only thing that I think can shorten my game is if I make sure that I get pyramids, hanging gardens, and a forge in the same city ASAP and get my GE's working quicker. Once I pop one of them I can turn out some scientists and artists from other cities. Try and time my 2nd GE near the end of mass media.
I think 1100 is the absolute minimum for this gauntlet. You would have to get lucky on huts to get anything before that. I will probably take some time off of the gauntlet now though. May try again before the end. Would like to get sub 1200.
BTW, city placement isn't that important. Try for a river area so you can get the extra cash and food is nice for fast growth. Avoid jungle though, it takes too long to clear. The closer you pack your cities together the cheaper it will be. You can overlap some hill squares as well.
