Perhaps you should try some spelling variations:
"race walking" » "hace walking", "nace walking", "rae walking", "race talking"
"grace walking" » "ghace walking", "gnace walking", "grae walking", "grace talking", "grade walking", "grave walking"
"trace taking" » "thace taking", "tnace taking", "trae taking", "trece taking", "trate taking", "trace making"
"traces taking" » "thaces taking", "tnaces taking", "traes taking", "treces taking", "trates taking", "traces making"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (((("race walking") OR ("grace walking"))) OR ((("trace taking") OR ("traces taking"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"race walking\") OR (\"grace walking\"))) OR (((\"trace taking\") OR (\"traces taking\"))))".
• Removing quotes may allow a broader search: (((( race walking ) OR ( grace walking ))) OR ((( trace taking ) OR ( traces taking )))).
• Adding a wildcard symbol may retrieve word variants: (((("race walking") OR ("grace walking"))) OR ((("trace taking") OR ("traces taking"))))*.
