Background:

Some rides required back-to-back challenges.  Here how the rules are applied:

1. Each leg of a back-to-back series must be completed start to finish in the time allowed for a single leg, AND all legs of a back-to-back series must be completed start to finish in less than the total time calculated by adding the time allowed for each independent leg in the series. The term "leg" refers to the individual rides of a back-to-back series.

For example, to claim a Bun Burner GOLD 3000, each leg of this ride must be completed independently in less than 24 hours, AND both legs in under 48 hours overall. To claim triple BBGs, each leg must be completed independently in 24 hours, AND all three legs in under 72 hours overall. To claim a CCC GOLD, each leg must be completed independently in 50 hours, AND both legs in under 100 hours overall.

On each leg, you must obtain a starting receipt AND an ending receipt.

2. Time left over from a previous leg in a back-to-back series may not be used to lengthen the time allowed for successive legs in the series. The clock for consecutive legs in a back-to-back series must be started exactly on or before the maximum time has expired for the previous leg in the back-to-back series.

Under rule 2 there are two options for handling the midpoint between consecutive legs. In one case a rider may use the ending time of the first leg as the starting time of the second leg. A rider who chooses this option they will be sacrificing any remaining time of the first leg. This valuable time could have been used for much needed rest.

The suggested method of handling the midpoint between consecutive legs is to use any remaining time on the first leg for rest. A rider may even rest beyond the maximum time allowed for the first leg.  Remember, the TOTAL ride must be completed in no more than the total time calculated by adding the time allowed for each independent leg in the series.
