How Indoor Insanity Works
To minimize injury and “traffic jams”, runners pick their preferred heat based on their general running speed.
- Heat # 1 – for the fastest runners (15-20 minute 5k) Field will be limited to 30 runners.
- Heat # 2 – for the intermediate runners (21-28 minute average 5k) Field will be limited to 75 runners.
- Heat # 3 – for runners of any level willing to take on the challenge that only chaos can bring!
- Walkers are welcome (we will have a dedicated lane for walkers).
- 1/2 mile Kids Fun Run, too!
Ribbons and bragging rights will be awarded to winners of the various heats. All participants have opportunity to win some terrific door prizes.
Race Timing and Lap Counting – Get Great Running Data
Indoor Insanity will be professionally chip-timed for accurate individual lap and finish times. Unlike other 5k races which give you just one finish time, Indoor Insanity 5K participants get 25 pieces of running data – split times for each lap completed.
Lap Counting: Hand tally counters will be available to help runners keep track of lap numbers. Please note: Even though the chip timing company does an AMAZING job of helping runners keep track of where they are in their race, Indoor Insanity participants should not rely on the chip timing company to provide individual lap counts during their heat. (It’s just not possible – it’s too insane!) If you are worried about lap counts, please bring a spotter with you.
