Radcliffe holds the world record marathon time, and likes the weather and support in Albuquerque, New Mexico.
"I'm heading to Albuquerque as I know it well, the weather is safe and I've got reasonable back-up there, both massage and medical. We go on 2 February after a few days' check-up in the UK and plan on staying eight weeks," she said.
According to the Guardian:
"Radcliffe has almost a full month's training under her belt already this year, although she recently lost a few days through sickness at her base in the French Pyrénées.
"We've been three weeks in Font Romeu and it went well until I got flu and missed last the last four days," said Radcliffe, who was accompanied by her husband and manager, Gary Lough, and her two-year-old daughter, Isla.
"I was enjoying running in snow and think it helped strengthen my legs. I was doing fast stuff on the treadmill and it was going well."
Now the 35-year-old marathon world-record holder is looking forward to heading off to another favourite location in New Mexico next Monday to intensify preparations for the London Marathon on 26 April.
After missing her favourite marathon through injury or because of the birth of Isla two years ago Radcliffe is determined to add to her victories achieved in 2002, 2003 and on her last appearance there, four years ago. A fourth success would match the number of wins achieved by Norway's Ingrid Kristiansen and would be a boost before attempting to regain the world title in Berlin this August."
