Bicyclists who have pedaled along East Riverside Drive know the experience can leave you quaking in your bike shoes.

But it’s an important east-west transportation route for many folks, and that’s why Bike Austin wants to draw attention to the need for protected bike lanes and pedestrian safety improvements there.

To do that, they’ve organized the Survive Riverside Ride.

Cyclists and pedestrians will gather at 1 p.m. Saturday at Midway Fieldhouse, 2015 E. Riverside Drive. They’ll pedal or walk from Midway Field House to Grove Street and back, and negotiate a Tough Mudder-style obstacle course highlighting the difficulties facing daily commuters who use it.

The road, at its widest, spans four lanes in each direction. Between 2010 and 2014, more than 30 people suffered serious injuries in crashes on the street. At least three pedestrians and bicyclists died.

Bike Austin staff, Riverside Drive residents and City Council Member Pio Renteria will speak at the event.
