I'm headed back myself on Saturday and can't wait to run the streets again. Such a great way to take in the city. Figured I'd just paste the list here in case anyone else ever needs it.
As far as hotels go, I only ever stayed in one place apart from my apartment, and that was Hotel Arenula (see below). It was ok, not great, but not too expensive. But that was back in 1999 or so, so who knows?
There's a place in Trastevere with only a few rooms (i.e.: it's small). Here's the website:
Hotel Smeraldo, near Campo de Fiori, is the place we most used for guests of our program:
Pensione Primavera (near Piazza Navona), featured on this web page:
There's also a religious order listed in the handbook. They offer
lodging to families and look pretty good to me:
Casa Santa Francesca Romana a Ponte Rotto
Favorable responses at Residenza Farnese and Residenza Argentina, in Largo Argentina.
You might also check hostelworld.com for apartments and so forth. It's very comprehensive in terms of listings.
As far as running routes go, There's Villa Pamphili, Villa Borghese, Via Appia Antica (one of the oldest roads in the world, with chariot wheel ruts embedded in the stones); Villa Ada and Caffarella. Those are all green spaces. I liked to run some pretty tough, relentless repeats up the Capitoline steps early in the morning (designed by Michelangelo). You can also try running loops in Circo Massimo (the site of chairot races, alla Ben Hur); You can run just about any street in the city but the tough part isn't the traffic, it's the pedestrians. If you want a track there's one next to the Baths of Caracalla.
I always enjoyed running the river, even though it's pretty nasty down there on the water's edge, especially in the summer—too much garbage, as well as other unspeakable remains from drunken revelers the night before. This is primarily a summer phenomenon. Stay high on the street and you'll enjoy the view of the water just as well: run along the Lungotevere north along the river until you reach Via Fernando Di Savoia. That will take you into Piazza Del Popolo, which leads up the hill to Villa Borghese—lots of good running there. Another great route is to start in Largo Argentina next to the ruins and the spot where Caesar was stabbed, head toward the Jewish Ghetto, follow the streets which pass the Capitoline Hill, Teatro Marcello and the Temple of Hercules, go left toward Circo Massimo at the foot of the Palatine Hill, and then another left to head straight toward the Colosseum. You can then head back to the center of the city by following Foro Imperiali toward Piazza Venezia. That's quite a spectacular route and you'll take in many important monuments along the way.
My favorite runs involved zig-zagging on the bridges over the Tiber river, hitting, especially, Ponte St. Angelo, with Bernini's ANgels flanking either side. Beautiful, beautiful, beautiful.
I belonged to a small gym called Spazio Danza just off Largo Argentina in the historic center—not well equipped but it was right around the corner from my place, which was two blocks behind the Pantheon. I have three public routes on logyourrun.com that I can share here:
But you can also just search for Rome as a location on logyourrun, dailymile.com or other sites and find plenty, I'm sure.
Have a great time! It's a beautiful city and running it ensures that you'll take in plenty with the intimacy of a walk but in half the time. If you want more information just drop me a line.
