ANSWER:

How would ghusl get invalid on the way to the masjid?! Most likely you mean whudhu! This has nothing to do with the reward. 

When walking to the Mosque with Ghusl for Jumuah, trying to get the reward of every step = 1 year praying and 1 year fasting, if the Ghusl gets invalid on the way, will we still get the reward?
