Four-time Olympic champion Michael Johnson is recovering after suffering a “mini stroke” last week.

The former sprinter, who previously held the 200 and 400 meters world records, revealed on twitter over the weekend   that he had suffered a transient ischemic attack.

However, Johnson added that he is making “great progress” and has taken the opportunity   to raise stroke awareness.

He adds  that  he  back at home with my family, cleared of any heart issues and have already made great progress on  the road to a full recovery.
