Need options for where to carb-up in readiness ahead of Marathon Monday, or where to replenish your depleted glycogen, après race? We've got the lowdown on the city's deals on bottomless pastas and delicious comfort food. And even if you're not running, no one's stopping you from indulging, too. 

In east Cambridge, the annual bottomless pasta marathon menu returns to Restaurant dante in the Royal Sonesta Hotel. On Sunday, otherwise known as Marathon Eve, dante’s annual Carb It Up Bottomless Pasta Marathon includes house-made pastas like chitarra alla Genovese with a classic pesto sauce; tufoli al sugo di pomodoro, with tomato and basil; spicy aglio e olio spaghettoni with pine nuts and raisins; or strozzapreti con le zucchine – a thick spaghetti type pasta with zucchini and Pecorino cheese. Go with these vegetable and cheese preparations or add meatballs, grilled chicken breast or grilled arctic char to amp up the protein. (Pastas $16-$24; meat sides $9, fish $12. Sunday. 40 Edwin H Land Blvd., Cambridge. 617-497-4200. www.restaurantdante.com.)

SRV, the Venetian-inspired restaurant in the South End, mills its flour in-house for all grain-based dishes, including pastas. (Freshly ground grains retain more nutrition.) SRV’s special marathon weekend “Arsenale” all-pasta tasting menu is a selection of cicchetti (Venetian tapas or small bites) from which diners choose four dishes: tajarin, with asparagus, truffle, and butter; gnudi with morels and pecorino; maltagliati with foraged mushrooms, leeks, and Parmesan; bigoli with a duck ragu and soffritto; or a spring radish salad with asiago. ($50. Friday through Sunday, dinner only. 569 Columbus Ave., Boston 617-536-9500. www.srvboston.com.)

For a casual fuel stop, Anthem Kitchen + Bar in Faneuil Hall has a Sunday and Monday marathon special that’s a steal: a bottomless bowl of orecchiette pasta with roasted vegetables in a light tomato-cream sauce. It’s available for lunch and dinner on both days. ($16. Sunday and Monday. 617-720-5570. 101 South Market Building, Boston. www.anthem-boston.com.)

On Monday, runners who bring their 2016 Boston Marathon medal to Serafina Boston, post-race, can enjoy an unlimited serving of any homemade pasta of their choice, including hearty Bolognese, homemade black truffle taglioni, and lobster ravioli. While you’re at it, try the fluffy ricotta cheesecake slavered in berries; or that traditional Italian pick-me-up, a slice of creamy tiramisu. You’ve earned it. (Pastas: $26.20. Desserts: $8-$10. Monday. 10 High St., Boston. 617-426-1234. www.SerafinaBoston.com.)
