The Four Seasons hotel (155 Ratchadamri Rd, 02-126-8866, www.fourseasons.com/bangkok) holds its 6th Cancer Care Charity Fun Run at Lumpini Park on February 23. There will be 5 km and 10 km routes suitable for runners and walkers of all ages, while various activities and games offer prizes. Registration is from 7am to 7.45am for an 8.05am start. There’s a minimum donation of B350, with proceeds going to research projects at the Hematological Cancer Research Centre at Chulalongkorn Hospital. Last year’s run apparently had 3,000 runners, and raised B3.7 million.
