Sprinting Towards Sustainability: An Amazing Race Adventure will let up to 10 teams of two people cycle, walk or run around the course in a bid to win two bicycles worth $600 each.
After finishing off five mystery sustainability tasks, participants can check out an eco-pavilion at The Forks Market, where activities will include a composting demonstration, vehicles on display and green prize giveaways.
Registration for Katz's Symposium on Sustainability kicks off Monday at 9 a.m.
The city says people who want to take part should call early, as the attendance is capped at 100.
To sign up, call 986-7367 or visit www.winnipeg.ca/MayorsSymposium.
The day-long symposium is happening Saturday, April 25 at the Winnipeg Art Gallery, 300 Memorial Blvd., from 8 a.m. to 5 p.m.
It's aimed at launching a year-long process to come up with a new official 25-year plan for the City of Winnipeg. The plan would be a successor to Plan Winnipeg, the city's long-term blueprint for land-use and planning.
Participants will share their views, take part in round-table discussions and hear from a panel of experts at the symposium.
The mayor's environmental reputation took a hit in recent months, with the chair and most members of his environmental advisory committee quitting in February over what they said was a lack of political clout and money.
Katz revived the panel later that month and put Transcona Coun. Russ Wyatt in charge.
