Dedicated bike path along river to 65th & Concord, then it goes along next to Concord to Kaposia Landing trailhead.
Follow the (MRT) trail some miles, eventually turning on Cahill, which takes you to Inver Grove Trail (road). Follow the bike trail along there past the Pine Bend School, & the trail turns away from the road again past the RR trestle. [easy to spot because there's an attractive awning over the trail to protect from train debris] ... After that, the trail follows Courthouse Blvd. a bit before turning off on to a dedicated, removed bike path again ...... the current trail ends near the beginning of Pine Bend Trail (which is a road, not a bike trail - nice shoulder, very low traffic). You can take Pine Bend for a mile or so ... turn Left on Fahey Ave (gravel, may not be signed or may say archery range). Take that a few hundred meters to the Fahey Ave Trailhead (well signed, cars parked, cyclists gathering, Q248+F3). From there follow the trail to Hastings. (The trail does not appear on Google Bicycle routes, I don't think Google is updating those.)
Another member shared their Strava map (125 miles - beyond me):
These are lovely bike trails, but the Kaposia trails cross roadways. Drivers may turn left or right off Concord without looking for pedestrians, much less a cyclist heading downhill at 30-45mph. (Like someone who didn't see spot the road crossing until they passed in front of a car that turned abruptly left without signaling but a miss is a good as a mile they say).
By comparison here are the parts Google knows about:
