Why not combine 2 of my favorite activities into one! Introducing the Run & Cube 5K --- a quirky twist on the usual 5K for all running geeks or geeky runners. Here's how it works:
When you sign in and pick up your bib number you will be given a 3x3x3 cube (similar to Rubik's Cube {tm}) that has been scrambled randomly. You can try and solve it before the race starts and/or during the race while you are running. Once you cross the finish line --- if you have solved at least one side of the cube --- you can present it to the timing crew and receive a bonus deduction from your race time.
Full size cubes with the race logo on them will be awarded to the fastest running cubers based on their final time after any deductions for solving one or more sides of the cube.
Run & Cube 5K Rules: Runners should work independently to solve their own cube. Runners can attempt to solve the cube before or during the race and if they solve at least 1 side of the cube can check in with the timers at the end of the race to receive their bonus time deduction. Time Deduction will be calculated as follows: 1 side = 1 minutes; 2 sides = 1.5 minutes; 3 sides = 2 minutes; 4 sides = 2.5 minutes; 5 sides = 3 minutes; ALL 6 sides = 5 minutes.
50% of the proceeds of this race will go towards the organization of the first ever speed cubing competition in the Madeira (a semi-independent small group of islands 200 miles off the coast of Morocco) and the other 50% will go to local school's Math Teams.
The race will be run on the usual Delta Dental 5K course in Concord NH. Refreshments will be available post race.
