The website is a little moody at times so here's what they say about the race:
"Teams of four people will travel through Prince George's County in this one-day contest, stopping at historic sites where they will face a series of unique and interactive history challenges--both mental and physical. When a team successfully completes an assigned challenge at a site, they will follow clues to the next secret historic destination. The first team across the finish line wins! Advance registration is required; the fee is just $30 per team of four people.
The Time Travel Challenge will be a combination of both physical and mental challenges. Some of the components of the race may include, but are not limited to:
Carrying objects up to thirty (30) pounds
Working with tools such as hammers and saws
Solving riddles or puzzles
