Paula Radcliffe has asked the British selectors to consider her for both the 4K and 8K races in this year's IAAF World Cross-Country Championships.
Radcliffe, twice winner of the gold medal over the longer distance, is currently having her fitness assessed after racing in Puerto Rico last weekend.
Before making any decision on whether to run in one or both races in Brussels on March 20-21, Radcliffe is having a virus she picked up before last Sunday's road race checked out.
The Bedford star, chasing a third victory in the `World's Best 10K' meeting in San Juan, was outsprinted at the finish by Kenyan-born Lornah Kiplagat of the Netherlands.
Several other leading athletes have asked the Norwich Union GB selectors to consider them although they will be missing from Saturday's trial race in Nottingham.
They include Radcliffe's training partner and Bedford team-mate Liz Yelling, one of the country's most experienced cross-country performers who wants to run the 8K event.
Definitely in the team is Jo Pavey who in Budapest on Friday qualified for Sunday's World Indoor Championships 3000 metres final.
Commonwealth 1500m bronze-medalist Helen Clitheroe also wants to run the shorter distance but John Mayock and Tom Mayo have declined places in the men's team at that distance.
