Extreme urban kayaking, with its gnarly taxi rapids, precarious pigeon speed bumps, and the incredible friction of asphalt, is a sport reserved for only the elite adrenaline junkie. Experience the easily accessible, non-extreme version of urban kayaking with today's deal: for $7, you get a $15 voucher for a kayak rental and a T-shirt (a $10 value) at Kayak Pittsburgh, a project of Venture Outdoors (a $25 total value). Today's deal is only valid on weekends from May 1 to May 23 and only on weekdays beginning Tuesday, June 1, through Friday, October 29.

Navigate multiple routes on two watery destinations around Pittsburgh. Select between the downtown location for skyline views or the scenic Lake Elizabeth location, which is Pittsburgh's oldest park and is great for beginners. Rental prices cost up to $20 an hour, depending on the kayak size (solo or tandem), the date, and the location you choose. Like the protocol for riding a Great Dane, all kayaking participants will be given basic safety instruction, need to wear proper safety gear (in this case, a life jacket), and must sign a risk-acknowledgment form. Prospective paddlers under 18 must have a parent or guardian sign as well.

Kayaking can be a relaxing jaunt or a stellar workout, depending on the paddle pace. Kayak Pittsburgh uses flat-water kayaks, which are longer and much more stable than whitewater kayaks and logs with saddles. Bring a driver's license as a deposit for the kayak. As you navigate the waterways, sport your sporty new Venture Outdoors T-shirt while building fonder water-based memories than the time Grandma fell off the side of the pontoon.

On World Environment Day (June 5), Venture Outdoors will attempt to break the world record for the largest flotilla (free-floating raft of kayaks and canoes), near Point State Park. Though your Groupon cannot be used for rental that day, use your newfound prowess to register for the event.

Kayaks are available on a first-come, first-served basis.
